Water Flow and Hidrolic Pressure Sensor - YF-S201

Water Flow and Hidrolic Pressure Sensor gives the number of tours of the the rotating propeller through the water flowing from within. The number of the rotating of the propeller is measured by using hall-effect which is in the sensor. It can be used with lots of microcontroller platforms such as Arduino through it is a digital output device. It can be preffered easily to measure the amount of flowing fluid at a coffee machine or garden irrigation system.
