1/2 inch Water Flow Sensor – YF-S201

1/2 Inch Water Flow Sensor – YF-S201

The YF-S201 Water Flow Sensor is a reliable and widely used flow measurement sensor designed for water monitoring and automation applications. It works by measuring the flow of water through an internal rotor and Hall Effect sensor, generating pulse signals proportional to the water flow rate. This sensor is commonly used in smart water management systems, water dispensers, industrial automation, irrigation systems, and IoT-based monitoring projects.

The sensor provides accurate and stable performance while maintaining low power consumption. Its compact size and easy interfacing make it ideal for Arduino, ESP32, Raspberry Pi, STM32, and other embedded development platforms. The YF-S201 is capable of handling moderate water pressure and is suitable for both DIY and industrial projects.

At RoboCircuitHub, we provide quality-tested electronic components and embedded solutions for students, makers, innovators, and industries. This water flow sensor is perfect for developing smart monitoring systems and automation products.
