Build your own industrial 24V DC Water leaks detections, to control shut-off valve or alarm, and save. 

Simply connect the W7 water sensitive board with additional 2 resistor (24K and 1M) as shown to the relay board. Connect 12V DC to power relay board or 24VDC via our 12VDC regulator board (as shown). Connect your valve or alarm to the relay contacts.

Mount and power it--and you're in business.
