1/2 Inch Water Flow Sensor – YF-S201

The YF-S201 water flow sensor is a device that is used to measure the flow rate of water. It consists of a turbine-type rotor that is placed in the water stream, and as the water flows past the rotor, it causes the rotor to spin. The sensor measures the speed of the rotor and converts it to a flow rate. The sensor has a digital output, which means that it provides a digital signal that can be read by a microcontroller or other host device.

The sensor is commonly used in applications such as irrigation systems, water treatment plants, and industrial process control. It is often preferred over other types of flow sensors because it is easy to install and has a low cost. Water flow sensors are installed at the water source or in pipes to measure the rate of flow and calculate the amount of water that has passed through the pipe. Water flow is measured in liters per hour or cubic meters.
