YF-B2 Water Flow and Temperature Sensor
The YF-B2 Water Flow Sensor is a meticulously engineered device, suitable for both domestic and industrial usage, intended to provide accurate measurements of liquid flow. Constructed with a robust copper body, the sensor incorporates a dependable Hall effect sensor for precise flow quantification.
As the liquid traverses through the sensor, the in-built rotor is set into motion, creating pulse signals that are directly related to the flow rate. These pulses are readily interpretable by microcontrollers, making the sensor a perfect candidate for inclusion in a variety of projects.
