YF-S201 1/2" Water Flow Hall Sensor
YF-S201 1/2" Water Flow Hall Sensor

Description of product


Water flow sensor can be used to measure the flow of liquids, i.e. the consumption of liquids in industrial or domestic usage. For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc. Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse Signal.
