AUTO BOTIX YF-S201 Water Flow Sensor With Magnetic Hall

The AUTO BOTIX YF-S201 Water Flow Sensor with Magnetic Hall is a widely used sensor for measuring the flow rate of liquids in various applications. It's often employed in projects that involve monitoring and controlling water usage, such as in irrigation systems, water dispensers, and other liquid management systems.

The YF-S201 is designed to measure the flow rate of water. It operates by having the liquid flow through the sensor’s body, which causes a rotor inside to spin. The rotor's rotation speed is directly proportional to the flow rate. The sensor incorporates a magnetic Hall effect sensor that detects the rotation of the rotor. As the rotor spins, the magnetic field changes, which is detected by the Hall effect sensor. These changes are converted into electrical pulses.
