Flow Rate Sensor Arduino

In this project use the yf s201 1 2 inch water flow sensor to measure the water flow rate l min and display it on an lcd.
Flow rate sensor arduino. The design is for an orifice type flow sensor the orifice in our case a washer provides a restriction and. The 5v vcc red wire the gnd black wire and the signal pulse usually yellow line. By using a flow sensor with a microcontroller like arduino we can calculate the flow rate and check the volume of liquid that has passed through a pipe and control it as required. We know that this sensor will output a pulse to arduino pin 2 every time the flapper rotates and every and that every rotation means 2 25ml of fluid has passed the sensor so calculating the flow rate is really just a matter of counting the revolutions per minute and multiplying by 2 25ml.
Apart from manufacturing industries flow sensors can also be found in the agriculture sector food processing water management mining industry water recycling. 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. In this tutorial you will learn how to use one water flow sensor with an arduino board. 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.
How to make an accurate air flow rate sensor with arduino for under 20 covid 19 ventilator. Connecting the arduino to the flow rate sensor. In this project we will interface yfs201 hall effect water flow sensor with arduino for measuring flow rate and volume of water or any other liquid this is a very wonderful project that can be used in industry or at home or at water flow measurement application in water tap tunnel river etc. Besides the arduino s serial monitor we also used our dso to measure pulse output from the water flow sensor.
When the water flows through the rotor rotor rolls and the speed of it changes with a different rate of flow. This instructables shows how to build an air flow rate sensor using a low cost differential pressure sensor and readily available materials. The water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor. The connections required for this flow rate sensor with respect to the arduino are very minimal.
