YF-S403 3/4 Inch Water Flow Hall Sensor (Digital Turbine Flow Meter)

The YF-S403 3/4 Inch Water Flow Hall Sensor is an inline liquid flow sensor designed to measure water flow using a turbine and Hall effect sensing technology. As water flows through the sensor, the internal turbine rotates and generates digital pulse signals proportional to the flow rate. The sensor provides a simple pulse output that can be read by Arduino, ESP32, STM32, Raspberry Pi (with GPIO), and other microcontroller platforms for real-time flow monitoring, water management, and automation applications.
