A simple sensor for measuring the flow of liquids. Consists of a pinwheel that has a magnet and Hall sensors. By counting the pulses of a hanging fan, in a simple way, you can measure the flow of liquids. With this method, the electronic part of the sensor has no contact with water.

The device has three wires:

• red - supply voltage from 5 V to 12 V
• black - ground
• yellow - pulse output signal

By counting pulses you can track the fluid flow in a simple way. It should be noted that this is not a sensor for precision measurements. However, it is ideal for use in hobbies that do not require greater accuracy than 10 %.
