YF-S401 Water Flow Sensor

The YF-S401 Water Flow Sensor is a sophisticated electronic device engineered to gauge the rate of water flow. It is composed of a plastic casing, a water flow rotor mechanism, and a Hall-effect sensor. The rotor spins as water passes through it, with its speed varying based on the flow rate. The Hall-effect sensor then identifies the speed of the rotor and transforms this data into a digital output signal.This sensor is ideal for a wide range of uses, including tracking water levels in reservoirs, managing water pump functions, enhancing the effectiveness of irrigation systems, and identifying water leaks.
