YF-B1 Water Flow Sensor

The YF-B1 Water Flow Sensor is ideal for both industrial and domestic applications, providing accurate measurement of liquid flow. This sensor features a durable construction and integrates a Hall effect sensor to deliver precise flow readings. The sensor's internal rotor spins as liquid passes through, generating pulse signals that are proportional to the flow rate. These pulses can be easily read by microcontrollers, making the sensor an excellent choice for a variety of projects.
