The YF-S201 G 1/2" Water Flow Sensor Module is a reliable and cost-effective solution for measuring water flow in pipes and fluid systems. Built with a Hall effect sensor, it generates a digital pulse output proportional to the water flow rate, allowing accurate real-time monitoring using microcontrollers such as Arduino, Raspberry Pi, ESP32, AVR, PIC, and 8051.

Designed for G 1/2 inch pipe connections, the sensor supports a wide flow rate range from 1 to 30 liters per minute, making it suitable for household water monitoring, industrial automation, and smart irrigation systems. Its plastic housing ensures corrosion resistance and durability, while the internal rotor provides consistent pulse generation even at low flow rates.

Operating over a wide voltage range of 5V to 18V DC, the YF-S201 is easy to integrate into various embedded systems. The sensor outputs pulses at approximately 450 pulses per liter, enabling precise calculation of flow rate and total volume with simple software logic.

Common applications include water dispensers, flow-based billing systems, smart water meters, irrigation controllers, liquid dispensing machines, robotics projects, and IoT-based water management solutions. Compact, efficient, and easy to install, the YF-S201 water flow sensor is an essential component for projects requiring accurate liquid flow measurement.
