How to Make Water Trickle out From Tap Automatically

One of our customer wants a motion detector controls a solenoid valve which works in a tank for hand-washing.


We recommend this smart infrared detector model of 0040101. The module can accurately detect any moving objects within the detective range and commonly be used to detect human body movement. It has higher sensitivity and broader detective range than others. The motion sensor detector will work with the solenoid valve.

Wire the solenoid valve to the detector according to the wiring diagram.

When someone puts his hands under the tap, the PIR motion sensor detector will detect and indicate the solenoid valve installed on the tap to open. The water will trickle out from tap for hand washing. It lasts about 20 seconds. The water will stop trickling out after 20 seconds.
