If you want to learn how to make a schematic and PCB then watch my tutorial, given below. This Water Flow Sensor is suitable to detect flow in water dispensers, water heaters, gardening or coffee machines. I will also explain the complete circuit diagram, making, and Arduino programming. my question is that everytime 1000ml will have different pulse count . Working on the Water Flow Sensor is a bit tricky whether you are using YF-S401 or YF-S201 Hall Effect Water Flow Sensor, and thats the reason, most of the people complain about the wrong values. The 12v DC Water Pump is controlled using a Pushbutton.
Without any further delay, lets get started!!! if water flow is high then pulse count may increase beyond 5880 pulse . The complete making of the whole setup is explained in the video tutorial given at the end of this article. For now, I will display values on the Serial Monitor. 
We also apply the calibrationFactor to scale the output based on the number of pulses per second per units of measure (litres/minute in this case) coming from the sensor. Note that because we've, // disabled interrupts the millis() function won't actually be incrementing right, // at this point, but it will still return the value it was set to just before, // Divide the flow rate in litres/minute by 60 to determine how many litres have, // passed through the sensor in this 1 second interval, then multiply by 1000 to, // Add the millilitres passed in this second to the cumulative total, // Print the flow rate for this second in litres / minute, // Print the integer part of the variable, // Print the cumulative total of litres flowed since starting, // Reset the pulse counter so we can start incrementing again, // Enable the interrupt again now that we've finished sending output, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window), Click to share on WhatsApp (Opens in new window), Click to share on Telegram (Opens in new window), Click to share on Tumblr (Opens in new window), Click to share on LinkedIn (Opens in new window), Click to share on Reddit (Opens in new window), Click to share on Pinterest (Opens in new window), Click to share on Pocket (Opens in new window), Click to share on Skype (Opens in new window), Download Water Flow Sensor Datasheet: yf-s401water flow sensor datasheet. I have been doing Job in UAE as a site engineer in an Electrical Construction Company. //note that sensorInterrupt (=0) variable is no longer used. As in this project, I am only covering the basics, so, thats why I didnt add any LCD. In the programming, I will be using the pulsein to measure the time of a pulse. Enter the email address you signed up with and we'll email you a reset link. digitalPinToInterrupt links pin to Interrupt without explicitly naming the Interrupt. The Water Flow Sensor for the Flow Rate and Volume Measurement using Arduino Uno, Mega or any other microcontroller board works on the principle of the Hall Effect. The flow of water or any other liquid should be in the direction of the Arrow. I solved this problem by using a 12v Water Pump. I have also defined a pin for the Solenoid valve, which you can use. The 12 volts are used to run the 12v DC water Pump.

I am really satisfied with this sensor. In this project, I have used the Arduinos Hardware Interrupt 0 which is available on pin number 2. At 1000mL you get 5880 pulses, but is that over a minute otherwise over a second its 5880/60 = 98 Hz square wave which has a period of 1/98 = 10.2 milliseconds. This rotor has a magnet which gives pulses to the Hall Effect Sensor. How you get 98 Hz ?? Your calculation is bit confusing for me. So how to get exact Calibration factor for water flow sensorif its not mentioned in datasheet also. Sorry, preview is currently unavailable. This schematic is designed in the Cadsoft eagle 9.1.0 version. I have doubt in water flow meter calculation. So for the pulses counting we will be using the Arduinos Hardware Interrupt 0. Adding a 162 LCD is very simple; you can watch my videos on how to use the 162 LCD. For 1mL you calculate 5880/1000 = 5.88/60 = 0.098Hz with a period of 10.2 seconds.
Later you can use a button to reset the value, instead of resetting the Arduino every time. For the water measurement, I will be using a feeder which is marked with 20, 40, and 60mL. I successfully performed all the tests. This Water Flow Sensor is simply amazing and highly accurate. The rest of the program is well commented. To browse Academia.edu and the wider internet faster and more securely, please take a few seconds toupgrade your browser. High Sealing Performance and this Water Flow Sensor has a High-Quality Hall Effect Sensor. Very interesting & neat project. 
Academia.edu no longer supports Internet Explorer. // Note the time this processing pass was executed. I get this error when I tried to run the script "TypeError: My name is Shahzada Fahad and I am an Electrical Engineer. The Red wire will be connected with the Arduinos 5 Volts, the Black wire will be connected with the ground and Yellow wire which is the signal wire will be connected with the Arduinos pin number 2, which is the interrupt pin. You can download the paper by clicking the button above. On the backside of this Water Flow Sensor, as you can see there is an arrow that shows the direction of the flow of water. A pipe from the bottle is connected with the inlet valve of the 12v DC Water Pump and the outlet opening of the 12v DC Water Pump is connected with the inlet opening of the Water Flow Sensor. Water Flow Sensor Arduino, Water Flow Rate & Volume Measurement- In this Tutorial, you will learn how to accurately measure the Water Flow Rate and Water volume using the Water Flow Sensor YF-S401, Arduino UNO, and a 12v DC Water Pump. Inside this Water Flow Sensor, we have a high-quality Hall Effect Sensor. Change all appearances of sensorInterrupt by digitalPinToInterrupt(sensorPin) to use it in ESP32. In this tutorial, I will also explain whats inside a Water Flow Sensor and how it works. The Water Flow Sensor 5v pin is connected with the Arduinos 5 volts, the Ground pin of the Water Flow Sensor is connected with the Arduinos ground and the signal wire is connected with the Arduinos pin number 2 which is the interrupt pin. The ground is directly connected with the Water Pump while the 12 volts are connected with the Water Pump through a Pushbutton. Its speed changes with different rate of flow. Configured to trigger on a FALLING state change (transition from HIGH, // Disable the interrupt while calculating flow rate and sending the value to the host. we depend on ad revenue to keep creating quality content for you to enjoy for free. So, the range of this sensor is 300mL to 6000mL per minute. So this side is the Inlet and this side is the Outlet. (adsbygoogle = window.adsbygoogle || []).push({}); Please Note: these are affiliate links. This sensor also has a rotor which rotates as the water flows from the inlet opening to the outlet opening. So I have changed code this way: // commented this > attachInterrupt(sensorInterrupt, pulseCounter, FALLING); //you can use Rising or Falling //changed to . This is the Water Flow Sensor which consists of a PVC body. When you open the serial monitor you will see 0mL. These three wires are connected as per the circuit diagram already explained. // Because this loop may not complete in exactly 1 second intervals we calculate the number of milliseconds that have passed since the last execution and use that to scale the output. The three wires of the Water Flow Sensor YF-S401 will be connected with the Arduino. if water flow is medium then pulse count can be between 5500-5800 or less like wise. I may make a commission if you buy the components through these links. As you can see the measured volume is 38mL. As per the datasheet, when water flows through the rotor, rotor rolls. Currently, I am running my own YouTube channel "Electronic Clinic", and managing this Website. If we can keep the pressure and flow constant we can make an accurate water volume measurement system. There are things that we need to take care of while using the Water Flow Sensor. Water Flow Sensor Arduino, Water Flow Rate & Volume Measurement, /*The hall-effect flow sensor outputs pulses per second per litre/minute of flow.
