YF-S201 Water Flow Sensor
Original price was: ₹350.00.₹260.00Current price is: ₹260.00.
(-26%)A water flow sensor that measures the flow rate of liquids using a Hall-effect sensor and a rotating turbine. It generates electrical pulses proportional to the water flow.
Product details
The YF-S201 Water Flow Sensor is widely used in water dispensing systems, smart irrigation, water monitoring, coffee machines, and industrial liquid measurement applications. As water passes through the sensor, an internal rotor spins and produces pulse signals through a Hall-effect sensor. A microcontroller (Arduino, ESP32, Raspberry Pi Pico, etc.) counts these pulses to calculate flow rate and total water volume.
