YF-B1 Water Flow and Temperature Sensor

The YF-B1 Water Flow Sensor is an exceptional tool for both industrial and residential uses, offering precise liquid flow measurements. It is built with durability in mind and incorporates a Hall effect sensor for accurate flow data. As the liquid flows through, the internal rotor of the sensor rotates, producing pulse signals that correspond to the flow rate. These pulses can be conveniently interpreted by microcontrollers, making this sensor a versatile component for numerous projects.
