Water Flow Sensor G1/4

Water Flow Sensor G1/4

The Water Flow Sensor G1/4 consist of magnetic core, a rotating impeller, an external casing and a hall-effect sensor. The principle is that when water flows through the inside, the rotor rotates and it enables the magnetic core to trigger action with the hall-effect sensor. This is to determine the rate of flow. The Water Flow Sensor G1/4 outputs corresponding pulse signals which the user can use to detect flow speed. This module is perfect for your Arduino projects to automate water or coffee dispenser. Here is the basic formula:

The water flow sensor outputs pulse proportional to the water flow with: Pulse Frequency = Flow* 98.That is, if the output frequency is 48, then the water flow: 48/98= 0.5(L/min).
