Water Flow Sensor (Sea) ZJ-S201 Flowmeter G1/2 1-30L/min White 5-24V

Water Flow Sensor (Sea) ZJ-S201 Flowmeter G1/2 1-30L/min White 5-24V is designed for electronics, IoT, robotics, and Arduino based applications. This module is easy to integrate with microcontrollers such as Arduino UNO, ESP32, NodeMCU, and Raspberry Pi. Suitable for educational, automation, industrial, and DIY electronic projects. Water flow sensor consists of a nylon valve body, a turbine impeller assembly and a hall sensor. When water flows through the impeller, impeller rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal.
