G1/2" Hall Effect Flow Sensor Switch Lithium which can switch automatically current

which can switch automatically current mode between the single-way communication mode and two-way communication mode according to the customer needs

but you can carry the 5 V for external use

which is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output

Dimensions:20 x 15 x 11 mm

and 3 pins

G1/2" Hall Effect Flow Sensor Switch Lithium which can switch automatically currentWater 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 flow rate. The hall effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine. We have a comprehensive line of water flow sensors in different diameters. Check them out to find the one that meets your need most.
