YF-B4 Water Flow Sensor with Temperature Sensor

The YF-B4 Water Flow Sensor is a versatile device suitable for both industrial and domestic applications to measure the flow of liquids. It comprises a durable brass body, a water rotor, and a Hall effect sensor. As water or liquid flows through the valve, the rotor spins, generating a pulse signal proportional to the flow rate.

The Hall effect sensor provides an electrical pulse with each rotation of the rotor. This sensor is isolated from the water pipeline, ensuring it remains safe and dry. The YF-B4 sensor module can easily interface with microcontrollers, Arduino boards, and Raspberry Pi.
