Description

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.

Description

The device has three wires:

  • red - supply voltage from 3.5 V to 24 V
  • black - ground
  • yellow - pulse output signal

Wires

  • red: - supply voltage from 3.5 V to 24 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 %.

The product is compatible with Arduino

The manufacturer has prepared aguidefor users of Arduino.
