There are only three wires coming from the flow rate sensor.
Air flow rate sensor arduino.
Besides the arduino s serial monitor we also used our dso to measure pulse output from the water flow sensor.
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.
How to make an accurate air flow rate sensor with arduino for under 20 covid 19 ventilator.
There are various methods of displaying this information.
The water flow sensor consists of a plastic valve body a water rotor and a hall effect 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.
Processed for calculation of flow rate.
The 5v vcc red wire the gnd black wire and the signal pulse usually yellow line.
The digital pulses of hall sensor are detected on arduino board.
The number of pulses is measured and.
In this case the information is displayed on an lcd and on the serial monitor of arduino.

The connections required for this flow rate sensor with respect to the arduino are very minimal.
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.
Connecting the arduino to the flow rate sensor.
