Water Flow Sensor (Sea) YF-S402C Flowmeter G3/8 0.3-10L/min 5-18V
The YF-S402C water flow sensor is designed to accurately measure liquid flow rates in various systems. Featuring a plastic valve body, flow rotor, and hall effect sensor, it is typically installed at the inlet to monitor water flow. As liquid passes through, the magnetic rotor spins, with the speed of rotation directly correlating to the flow rate. The hall effect sensor then converts this motion into a pulse-width signal that reflects the flow rate.
By connecting the sensor to a microcontroller, you can easily track the flow of water in applications such as coffee makers, sprinkler systems, and other water-dependent devices. This setup allows for precise control and monitoring of water flow, enhancing efficiency and ensuring the optimal functioning of water-based systems.
