YF-S201 1/2 Inch Water Flow Sensor (Hall Effect Flow Meter)

The YF-S201 1/2 Inch Water Flow Sensor is a compact flow measurement sensor designed to monitor the flow rate and total volume of water in pipelines. It uses an internal turbine rotor and Hall effect sensor to generate pulse signals proportional to the water flow. The sensor is compatible with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms, making it ideal for water dispensers, irrigation systems, water purification units, industrial automation, and IoT-based flow monitoring applications.
