Mechanical water flow switch detecting flow between 1 and 30 L/min. Ideal for home automation and leak detection safety systems.
The YF-S201 (MR-W1-P) water flow switch is a mechanical device that opens or closes an electrical circuit based on the flow of water through its tube. It serves as a simple yet effective way to detect fluid presence, absence, or volume in piping systems.
This module is commonly used in home automation projects, water level monitoring, and leak detection safety systems. It is installed directly in series with the water pipe.
