YF-B2 Water Flow Sensor

The YF-B2 Water Flow Sensor is designed for both industrial and domestic applications to accurately measure liquid flow. This sensor is built with a durable copper body and features a reliable Hall effect sensor to provide precise flow measurements. As liquid flows through the sensor, the internal rotor spins, generating pulse signals proportional to the flow rate. These pulses can be easily read by microcontrollers, making the sensor ideal for integration into various projects.
