Overview
The YF-S201C is a water flow sensor that measures liquid flow rates. It consists of a plastic housing, a rotating impeller, and a Hall effect sensor. It has a flow rate of 1 to 30 Litres per minute and can handle maximum pressure of 1.75 megapascals.
How it works?
It has a rotor (a.k.a impeller) inside and as the water flows through the sensor, it pushes against the blades of the rotor causing it to spin which has a magnet attached to it. The faster the water flows, the faster the rotor spins along with the magnets. These rotations are sensed using a hall efect sensor which can detect the magnetic field and is positioned near the rotor.
As the magnet on the rotor spins past the Hall effect sensor, it creates a disruption in the magnetic field. The Hall effect sensor detects this change and outputs an electrical signal, typically a pulse. The number of pulses generated by the sensor is directly related to the speed of the rotor, which in turn, is related to the flow rate of the water.
