water flow sensor consists of a plastic valve with two fittings with 1/2 inch of water a rotor and a Hall sensor. As the water passes through the sensor, the rotor rotates at a speed proportional to the rate of water flow. Hall sensor captures every turn and transmits the received signal.
In order to use water flow sensor to collect on the basis of its layout - install the sensor in the pipeline, connect the power supply, connect the microcontroller to calibrate parameters and start working.
The sensor requires careful calibration if required measurement accuracy greater than 10%.
The sensor must be connected to the system in the direction of fluid flow indicated by the arrow on the sensor housing.
Suitable for pipes and hoses with a diameter of 1/2 inch thread.
water flow sensor (meter) has one 3-pin connector.
Connection:
- VCC - power supply;
- GND - common contact;
- PWM - sensor output signal (pulse width modulation).
The sensor is powered by Arduino or controller, or other control microprocessor device, or an external power supply (power supply, battery).
water flow sensor is used to measure the flow of fluid passing through it in simple projects on microcontrollers. For example, solar cooling, water cooling computer system of irrigation garden plot, etc.
