Water Flow Sensor YF-S201, 1-30L/min Detection, Hall Effect Sensor, compatible with Arduino, ESP, Raspberry Pi

The YF-S201 Water Flow Sensor is a compact and reliable device designed to measure the rate of water flow in a system. Ideal for DIY electronics projects, home automation, and industrial applications, this sensor provides accurate real-time flow rate data using a simple digital output signal.

Equipped with a rotor and a Hall-effect sensor, the YF-S201 outputs a pulse each time water flows through it. The pulse frequency is directly proportional to the flow rate, allowing microcontrollers like Arduino, ESP32, or Raspberry Pi to easily calculate liters per minute (L/min).
