Good quality product
I am using it from last 4months and the sensor works flawlessly
The SEN-HZ21WA 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 flow 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. The SEN-HZ21WA sensor is designed to be installed in a pipe with a diameter of 1/2 inch (12.7mm).
A pinwheel inside the sensor moves as the liquid flows through the sensor. A hall effect sensor within the sensor senses the rotation of the pinwheel and outputs a digital pulse for every rotation. By counting the pulses from the sensor, you can easily sense liquid flow through the sensor. This allows easy interface to microcontroller, Arduino, Raspberry Pi, etc.
