The digital pulses of hall sensor are detected on arduino board.

Air flow rate sensor arduino.

The number of pulses is measured and. Connecting the arduino to the flow rate sensor. Link sketch download https gith. There are only three wires coming from the flow rate sensor.

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. There are various methods of displaying this information. How to make an accurate air flow rate sensor with arduino for under 20 covid 19 ventilator. In this case the information is displayed on an lcd and on the serial monitor of arduino.

Besides the arduino s serial monitor we also used our dso to measure pulse output from the water flow sensor. The design is for an orifice type flow sensor the orifice in our case a washer provides a restriction and. In this tutorial you will learn how to use one water flow sensor with an arduino board. The hall effect sensor outputs the corresponding.

The 5v vcc red wire the gnd black wire and the signal pulse usually yellow line. This instructables shows how to build an air flow rate sensor using a low cost differential pressure sensor and readily available materials. Best arduino flow rate sensor tutorial for beginner in thie video how to use water flow rate sensor with arduino uno board. 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.

The water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor.
