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.
Air flow rate sensor arduino.
There are only three wires coming from the flow rate sensor.
Link sketch download https gith.
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.
When the water flows through the rotor rotor rolls and the speed of it changes with a different rate of flow.
Connecting the arduino to the flow rate sensor.
This instructables shows how to build an air flow rate sensor using a low cost differential pressure sensor and readily available materials.
The hall effect sensor outputs the corresponding.
Besides the arduino s serial monitor we also used our dso to measure pulse output from the water flow sensor.
The number of pulses is measured and.
The water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor.
How to make an accurate air flow rate sensor with arduino for under 20 covid 19 ventilator.
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.
Best arduino flow rate sensor tutorial for beginner in thie video how to use water flow rate sensor with arduino uno board.
The connections required for this flow rate sensor with respect to the arduino are very minimal.
There are various methods of displaying this information.
In this case the information is displayed on an lcd and on the serial monitor of arduino.
