ultrasonic water flow sensor arduino

As said before, we transmit short ultrasonic pulse and we measure travel time of that pulse from transceiver to liquid and back to transceiver. First, let us talk about some theory behind ultrasonic method of fluid lever measuring. Adafruit Industries, Unique & fun DIY electronics and kits Liquid Flow Meter - Plastic 1/2 NPS Threaded ID: 828 - Measure liquid/water flow for your solar, computer cooling, or gardening project using this handy basic flow meter. Because of that (radar signals are high RF signals) it is not suitable for DIY. Are you looking to control your tank water level automatically here's the post for you, how can water level be controlled automatically? The aluminium case and grille corrode and the internals of the piezo electric transducer eventually gives up. Arduino - FLOOD ALARM - Using a Simple Water Level Sensor : Hello world! For damage occurred during reproduction I am not hold responsible. 8 months ago. Learn How to interface a YF-S201 Water Flow Sensor with Arduino. CeramTec presents its ultrasonic flow sensors, ideal for use in ultrasonic metering of gas, water and sub-metering applications. this is code for 3 sensor.int trig1 = 22;int echo1 = 23;int trig2 = 28;int echo2 = 29;int trig3 = 26;int echo3 = 27;void setup() { Serial.begin(9600); pinMode(trig1, OUTPUT); pinMode(echo1, INPUT); pinMode(trig2, OUTPUT); pinMode(echo2, INPUT); pinMode(trig3, OUTPUT); pinMode(echo3, INPUT); }void loop() { long t = 0, h = 0, hp = 0, t2 = 0, h2 = 0, hp2 = 0, t3 = 0, h3 = 0, hp3 = 0; // Transmitting pulse digitalWrite(trig1, LOW); delayMicroseconds(2); digitalWrite(trig1, HIGH); delayMicroseconds(10); digitalWrite(trig1, LOW); // Waiting for pulse t = pulseIn(echo1, HIGH); // Calculating distance h = t / 58; h = h - 6; // offset correction h = 50 - h; // water height, 0 - 50 cm hp = 2 * h; // distance in %, 0-100 % // Sending to computer Serial.print(hp); // Serial.print(" cm\n"); Serial.print("\n"); // Transmitting pulse digitalWrite(trig2, LOW); delayMicroseconds(2); digitalWrite(trig2, HIGH); delayMicroseconds(10); digitalWrite(trig2, LOW); // Waiting for pulse t2 = pulseIn(echo2, HIGH); // Calculating distance h2 = t2 / 58; h2 = h2 - 6; // offset correction h2 = 50 - h2; // water height, 0 - 50 cm hp2 = 2 * h2; // distance in %, 0-100 % // Sending to computer Serial.print(hp2); // Serial.print(" cm\n"); Serial.print("\n"); // Transmitting pulse digitalWrite(trig3, LOW); delayMicroseconds(2); digitalWrite(trig3, HIGH); delayMicroseconds(10); digitalWrite(trig3, LOW); // Waiting for pulse t3 = pulseIn(echo3, HIGH); // Calculating distance h3 = t3 / 58; h3 = h3 - 6; // offset correction h3 = 50 - h3; // water height, 0 - 50 cm hp3 = 2 * h3; // distance in %, 0-100 % // Sending to computer Serial.print(hp3); // Serial.print(" cm\n"); Serial.print("\n"); delay(1000);}, Hi,Thanks for the inspiration !I made some adjustments to send the data on mqtt. Water Flow Sensor Measure on 16x2 LCD Display - Arduino Project Hub Water Flow Sensor Measure on 16x2 LCD Display © GPL3+ In this project, use the YF-S201 1/2-inch water flow sensor to measure the … You may need to ignore this time by including it into dead zone as @andytechdude mentioned. Before installing sensor in tank we tested it for those two disadvantages. Is this sensor suitable or can you suggest a better sensor for the project? Besides the Arduino’s serial monitor, we also used our DSO to measure pulse output from the water flow sensor. We didn’t implement this because there was no need for it. About: I am an engineer and a maker who loves technology challenges. This is a project I put together that is basically two sensor stations: a base and a remote station. Because water has higher density, majority of pulse will bounce off. Then we opened a valve and let all the water run out. Step 4 Download SR04 Library and Install to Arduino IDE. This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced. First we transmit signal and then we wait and measure time between transmitted signal and received signal. Has anyone figured out how to make it water proof/humidity proof as this will be very clos eto water and even if we cover everything in epoxy or something of that sort HC SR04 will still be exposed. We can conclude that sensor works in accordance with expectations. There are water proof versions as used on car reversing devices but their sesitivity is much lower than the cheap common open versions. This is codified into 0 to 100 %. example code, circuit, pinout, library Question Are you willy? I'm trying this for my school project, please help me whit code.I can't download the code.please can anyone help me with code for this project? In this tutorial we will be hooking up a Flow Sensor to an Arduino Uno to measure liquid flow. (Take some pictures of your project living in the wild!). I am researching on building a fuel level remote sensing system. I checked, the water tank is empty and I have to call the water engineer to fix the water. Connect Echo to digital pin 6 on your Arduino board. - 2nd: because of the beam width we are limited with tank diameter. You see, outgoing flow in the tank depends on hydrostatic pressure inside of the tank. Because drain pipe is mounted to prevent sucking out sediments, tank was emptied to 2%. You need to download another Library to … When attempting to detect in the coser ranges, problems can be encountered due to cross-talk directly between the tranducers. How to make Ultrasonic Water Level Indicator Arduino Ultrasonic water level indicator mainly consists of an HC-SR04 ultrasonic module, which is used for non-contact distance readings. In this tutorial you will learn how to use one water flow sensor with an Arduino board. 2 years ago. … I personally would look into approved technologies such as those used in vehicle fuel tanks and adapt to suit your own application. Connect the +5V pin to +5v on your Arduino board. When the thermistor is cooled by more flow… The Automatic Water level controller is a device used to control the water level using a micro controller. Question . You have to put the water flow sensor to pin D1 and D2 ONLY, because the water flow sensor needs to use interrupts and for Arduino UNO it's only available on pin D1 and D2. Past work experience with the cheap readily available ultrasonic transducers has taught me that they do not like water. An Ultrasonic sensor is used in the transmitter circuit, which measures the distance of water level from the upper point of the bottle or Tank. We could also calculate water volume that is still in the tank. The complete water flow sensor Arduino code is given at the bottom of the page. Next we connected the water flow sensor’s output to the Arduino board (filled with the sketch) and allowed water flow through the water flow sensor at a steady rate of about 1 Litre/minute. Optical method can be very accurate, but sensors can get dirty over time and we are not able to make measurement at all. A few tips for increasing the life of these open transducers. The Ultrasonic Sensor: ... that way 3 Arduino pins allowed me to control 32 water pumps, and for the analog pins i used 5 multiplexers, 1 Master, and 4 slaves, that way using 6 digital and 1 analog pin of my Arduino i could control 32 sensor inputs. There will be no interrupt signal seen at the pin 2 of the Arduino, … Because sensor is measuring water level with contactless method water can stay unspoiled. int water_distance2 = water_bottom2- water_top2; attachInterrupt(digitalPinToInterrupt(flowPin), Flow, RISING); attachInterrupt(digitalPinToInterrupt(flowPin2), Flow2, RISING); rain_percentage = 100 * ((rain_distance - rain_level)/rain_distance); count++; //Every time this function is called, increment "count" by 1, count2++; //Every time this function is called, increment "count" by 1, noInterrupts(); //Disable the interrupts on the Arduino, count = 0; // Reset the counter so we start counting from 0 again, interrupts(); //Enables interrupts on the Arduino, flowRate = (getcount * 2.25); //Take counted pulses in the last second and multiply by 2.25mL, flowRate = flowRate * 60; //Convert seconds to minutes, giving you mL / Minute, flowRate = flowRate / 1000; //Convert mL to Liters, giving you Liters / Minute, flowRate2 = (getcount2 * 2.25); //Take counted pulses in the last second and multiply by 2.25mL, flowRate2 = flowRate2 * 60; //Convert seconds to minutes, giving you mL / Minute, flowRate2 = flowRate2 / 1000; //Convert mL to Liters, giving you Liters / Minute, //Serial.println(flowRate); //Print the variable flowRate to Serial. Refering to your comments regarding the longevity of the system. The explanation of the code is as follows. The acrylic will reflect part of the ultrasonic and the rest will go further and get detected when it comes back. In our program, we have displayed the distance measured by the sensor in inches and cm via the serial port. We have also made equation whit which we can measure volume of water still in the tank. Claim this project and add it to your profile. Two disadvantages exist with ultrasonic method: - 1st: because of pulse length there is small window that we cannot receive pulse with transceiver because transceiver is transmitting. This time is then converted to centimeter and centimeters are then converted to % and send via serial connection to computer. This sensor sit in line with your water line, and uses a pinwheel sensor … // Give a short LOW pulse beforehand to ensure a clean HIGH pulse: digitalWrite(trigPin, LOW); delayMicroseconds(5); digitalWrite(trigPin, HIGH); delayMicroseconds(10); digitalWrite(trigPin, LOW); // Read the signal from the sensor: a HIGH pulse whose // duration is the time (in microseconds) from the sending // of the ping to the reception of its echo off of an object. If tank diameter is too small, signal could bounce of tank’s walls and could cause false readings. int rain_distance = rain_bottom - rain_top; #define VIRTUAL_PIN_ULTRASONIC_PERCENT_1 V5. Optical method uses optical signals. We soldered wires to ultrasonic sensor (we used FTP or UTP cable; it can be one of them). We are showing how to use DS18B20 one wire water proof temperature sensor using Arduino. avrdude: stk500_recv(): programmer is not responding, avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 3 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 4 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 5 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 6 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 7 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 8 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0x68, avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x68. Implemented meter is also cheap and accessible and because of this it is very suitable for DIY. We made water level meter with Arduino platform (we used Arduino Mega2560, but any arduino will work). does this applicable for bigger tanks like water tanks. In the project two circuits are used, First is the transmitter and second is the receiver. Then we installed sensor in small custom made housing from acrylic glass. Cayenne.virtualWrite(VIRTUAL_PIN_ULTRASONIC_1, duration); water_percentage = (100 * (water_top + water_distance - duration)) / water_distance; Cayenne.virtualWrite(VIRTUAL_PIN_ULTRASONIC_PERCENT_1, water_percentage); Cayenne.virtualWrite(VIRTUAL_PIN_ULTRASONIC_2, duration); water_percentage2 = (100 * (water_top2 + water_distance2 - duration)) / water_distance2; Cayenne.virtualWrite(VIRTUAL_PIN_ULTRASONIC_PERCENT_2, water_percentage2); previousMillisUltraSonic = currentMillisUltraSonic; Cayenne.virtualWrite(VIRTUAL_RAIN, rain_percentage); Claim this project and add it to your profile. pinMode(echoPin, INPUT); duration = pulseIn(echoPin, HIGH); // Convert the time into a distance distance = (duration / 2) / 29.1; // Divide by 29.1 or multiply by 0.0343 restdistance = heightwell - distance; radius = diameter / 2; restvolume = (3.14 * (radius * radius) * restdistance) / 1000; percent = (restvolume / volume) * 100; Serial.print("distance: "); Serial.print(distance); Serial.print("cm "); Serial.print("restvolume: "); Serial.print(restvolume); Serial.print("L "); Serial.print("percent: "); Serial.print(percent); Serial.print("%"); Serial.println();//Message String char distString[5]; dtostrf(restvolume, 4, 0, distString); char percString[5]; dtostrf(percent, 4, 0, percString);//End Water Measuring//MQTT Begin // Ensure that we are subscribed to the topic mqttClient.subscribe(WaterVolume); // Attempt to publish a value to the topic if(mqttClient.publish(WaterVolume, distString)) { Serial.println("Publish Volume success"); } else { Serial.println("Could not send Volume :("); } // Ensure that we are subscribed to the topic mqttClient.subscribe(WaterVolumePercent); // Attempt to publish a value to the topic if(mqttClient.publish(WaterVolumePercent, percString)) { Serial.println("Publish VolumePercent success"); } else { Serial.println("Could not send VolumePercent :("); } // Dont overload the server! Right now I can only say that sensor is working fine within this short period of time. Please feel free to comment and let me know if I made any grammar mistakes (english is not my first language). hi, can someone write a code for multiple sensor? This procedure is ideal for our needs because ultrasonic sensors are accessible and low priced. With tank’s flow characteristic we can calculate how much water can flow out of tank at any time and with that we can determine how long valve must stay in open position. In picture is presented response to step function. An Ultrasonic water level sensing … The YFS201 is a popular water flow sensor, which we have previously used to measure water flow using Arduino and calculated rate of flow and volume dispersed. Remote & Base Sensor Station - Now with IoT! This problem is simple to solve: we placed our sensor higher from maximum water level for few centimeters allowing receiver to start receiving. Help me. I was choosing from contact and contactless methods of measuring fluid level in tank. Software can be modified to include a "dead zone" an echo time interval below which the readings are ignored. Its using ultrasonic to determine the distance from sensor to water and will be attached to some sort of wood above the water. * The echo terminals receives the ultrasound pulses and the sensor … Orange tanks distribute the water using a small pump to home. After that test we would be able to see if sensor is appropriate for use in DIY projects or any other environments. 2 years ago. Connect GND with GND on Arduino. Sometimes when I take a bath, the water stops. Quick question. I used pins 8 and 9 for this setup.the code ;):#include #include #include // Function prototypesvoid subscribeReceive(char* topic, byte* payload, unsigned int length);// Set your MAC address and IP address herebyte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };IPAddress ip(192, 168, 1, 160);// Make sure to leave out the http and slashes!const char* server = "192.168.1.16";// Ethernet and MQTT related objectsEthernetClient ethClient;PubSubClient mqttClient(ethClient);//Begin Water Measuring// fill in you're measurements int heightwell = 200; //inside height of the well in cm int diameter = 235; //inside diameter of the wel in cm int volume = 8760; //total volume of the well (measuring from the bottom to the lower edge of the overflow)(volume of cilinder = pi*r²*height) long WaterVolume = "WaterVolume"; //mqtt topic for the volume long WaterVolumePercent = "WaterVolumePercent"; //mqtt topic for the % int trigPin = 9; // Trigger int echoPin = 8; // Echo float restvolume; int liters; int restdistance; int radius; int percent; long duration, distance;//End Water Measuringvoid setup(){ Serial.begin (9600);//Begin Water Measuring//Define inputs and outputs pinMode(trigPin, OUTPUT); pinMode(echoPin, INPUT);//End Water Measuring // Start the ethernet connection Ethernet.begin(mac, ip); // Ethernet takes some time to boot! Contact methods are resistive method, capacitive and inductive methods (magnetostriction). Wireless water levelindicator using ultrasonic sensor Arduino is and amazing and very useful paper. We made water tank from drainpipe 1m in length and 16 cm in diameter. You can use it to count flow and volume of liquids and gases (although the documentation focuses on applications using liquids) and can support multiple flow sensors … Starting point of codifying is measurement alone. If we would want to use this meter in DIY project and in semi industrial or other applications we would have to make test of sensor endurance and resistance to water splattering. The water from the underground flows into, using Grundfos pump, it's filtered with sand and then goes through the. Because we didn’t want to affect the quality of water in tank we implement one of the contactless methods. Features on a tank wall or the rim of a hole for example. Implemented water level meter serves as a concept of principle. Upper section will serve as water tank. I suspect the sensors could be covered with food-wrap film to splash proof them without interfering too much with their operation.I'll be trying it! Watering system will use free fall for water feeding. Pulse … Inventing is fun but all engineering comes with a responsibility for safety. You can check the thread here, Note: WARNING! i made it, Thanks for the inspiration. Arduino Water Flow Sensor Working In our project, we connected the water flow sensor to a pipe. Question Cayenne.virtualWrite(VIRTUAL_PIN_WATERFLOW_1, flowRate); Cayenne.virtualWrite(VIRTUAL_PIN_WATERFLOW_2, flowRate2); unsigned long previousMillisUltraSonic = 0; unsigned long currentMillisUltraSonic = millis(); // Check sensor data every 250 milliseconds, if (currentMillisUltraSonic - previousMillisUltraSonic >= 5000) {. 1 year ago, Hello, can this same procedure be used to determine the level of gas in a gas bottle,? // Water Flow --> Only Works ON Pin 2 and Pin 3 for Uno, check https://www.arduino.cc/en/Reference/AttachInterrupt, int flowPin = 2; //This is the input pin on the Arduino, Only Can be setup in Port 2 and 3. double flowRate; //This is the value we intend to calculate. This part is essential, because we want to codify fluid height measurement in %. How can I send the signal and receive the echo to Arduino in 4 meters of distance?Thank you! My current water system has 2 water tanks. Thankyou. Minimum detection range. What is the maximum depth that we can measure using this sensor ? Sometimes the water from the ground is not flowing into the blue tank, so I need the water flow sensor in order to know whether the Grundfos Pump is flowing the water or not. All About Water Systems: Ultrasonic/WaterFlow/Rain Sensor, http://community.mydevices.com/t/please-make-support-for-arudino-uno-wifi/1586/6, https://www.arduino.cc/en/Reference/AttachInterrupt, IOT Based Water Manangment Flownomo and D’Smart_Switch, How To Use DS18B20 Water Proof Temperature Sensor, Single Device to Control Many Arduinos with NRF24L01+ Sensor. We filled up water tank to maximum height. That means, we must install our sensor 5 cm higher then maximum water level. Reply Can i measure the volume of an irregular shaped tank?Thanks Ben. Instead of radar wave we are sending ultrasonic wave. We have as example Arduino sketch that can be used to quickly test the sensor, it will calculate the approximate flow of water in liters/hour. 4. Trial & error is the only easy method for the home inventor for getting this right. We converted program for measuring distance to program for measuring water level. There is a definite optical difference between water or air in most tubes. Program for measuring distance is not of our making but was found on internet in this tutorial we cannot find anymore. Radar method uses radar signals. The ultrasonic sensor sends 8 pulses of 40KHz via the trig terminals (inaudible to humans, it's ultrasounds). The sensor's … Utrasonics have strange properties and what may look opaque to you may be perfectly transparent to utrasonics. (, means full flood, please prepare your boat because the flood has already reach the top of the roof T_T, //Remove This Someday when UnoWifiDev can connect to Cayenne (Can't Wait That Time Comes ^^), //#define CAYENNE_DEBUG // Uncomment to show debug messages, //#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space. 3. Answer Similarly as you can with light, reflectors and baffles may be applied to tranducers to shape / limit the beam. Diameter of pipe is the same through the length of the pipe. If the output valve of the pipe is closed, the output of the water flow sensor is zero (No pulses). 1 Contactor Schneider LC1D09M7 220V for Grundfos Pump, 1 MY2 AC 220V/240V - 5A DPDT Electromagnetic Power Control Relay OMRON, 1 Rain Sensors (This is Bonus because in the Future I want to develop the system if Rain comes I want to all windows closed automatically), If orange tank's below 75%, turn on blue switch (Grundfos Pump), If orange tank's above 95%, turn off blue switch, If blue tank's above 95%, turn off blue switch, If orange tank's below 50%, send email alert (there is some problem present in the water systems), Turn on blue switch (Grundfos Pump) at 5 am - 6 am (the lowest electrical use in my home). Receiver circuit receives the data from transmitter circuit and converts it in terms of the percentage and shows on LCD. int water_distance = water_bottom - water_top; #define VIRTUAL_PIN_ULTRASONIC_PERCENT_2 V7. Your transducers can "look" in through a well placed hole while enjoying the fresh dry air outside the tank. If the water flow sensors detects slower than usual flow, it means either I need to tweak the 'pipe button' or fix the underground pipe. delay(3000); // Set the MQTT server to the server stated above ^ mqttClient.setServer(server, 1883); // Attempt to connect to the server with the ID "myClientID" if (mqttClient.connect("myClientID")) { Serial.println("Connection has been established, well done"); // Establish the subscribe event mqttClient.setCallback(subscribeReceive); } else { Serial.println("Looks like the server connection failed..."); }}void loop(){ //Begin Water Measuring // The sensor is triggered by a HIGH pulse of 10 or more microseconds. HC-SR04 measures distances of 2cm to 400cm. Is the water clear? We established that we could have stable measurements from minimum distance of 5 cm from sensor. Share it with us! The reduced sensitivity may be OK for shorter range and larger targets that produce larger echo. 2. Ultrasonic method is similar to radar. We also established that we didn’t have any problems with signal bouncing from tank’s walls with 7.5 cm diameter tank (tank’s length was 0.5 m). or you need to make two holes for each sensor ? So now, with Cayenne, I have an idea to make My Water System connected to my mobile device. For larger stability we added wooden base, which will also house electronics and battery pack. Sometimes when I take a bath, the water stops. Isolating the transmitter and receiver sound can also help with this problem. With water, there is a more pronounced lens effect, I believe. 1/ Prevent water spray onto the transducer. The FloNoMo device solves the problem of overflowing tanks. For my next big project (automated plant watering system) I was in need of having water level meter. The pulse signal is a simple square wave so its quite easy to log and convert into liters per minute using the following formula. using YF-S201 Sensor. The components are all on Arduino shields to reduce as much … Orange tanks distribute the water using a small pump to home. Excellent idea! can this sensor pass sound wave through arcylic sheet ? Because in the future we wish to implement automatic watering system with two stages regulator, we must measure tank’s flow characteristic. We chose homogeneous tank because of easier calculations of volume (we are using pipe – cylindrical shape). HI Von,I hope you're doing good..You installed ultrasonic sensor just above the water and that sensor is constantly getting water vapours and moisture.. My question is, does that moisture damage the ultrasonic sensor .. Kindly reply me on my email hamzahashmi33@gmail.com.Thanks and regards. instead of placing the transducer above the liquid level guess it will be placed at the bottom. Thanks. Hi Everyone !I have a question about the Ultrasonic sensor.I have a water-box and I’d like to measure how fill is using the HC-SDO4 sensor with ArduinoIt is all set and in my protoboard the sensor works well, but when I try to connect to sensor through a 4way wire it is not working.The water-box (and the sensor is inside in a dry place of course) is 4 meters from the Arduino, wired connected.My question is, Does have any limitation in distance to connect the sensor through a wire?If yes, what you suggest me to do? You can figure it out somehow by yourself. Ultrasonic pulse will bounce from liquid level since because change of density of ultrasonic pulse travel medium (ultrasonic pulse first travel through air and bounce of liquid with higher density than air). 11 months ago, HelloYou have displayed vast knowledge of the project. FlowMeter is an Arduino library that provides calibrated flow and volume measurement with flow sensors. The coarse nylon material that pan scrubbers are made from produces a good barrier that drains easily and the transducer simply "sees" straight through. Reply Because of that, water tank needs to be lifted up from floor level.
