This wired water leak sensor comes with a 2 meter long cable, and connects to the THRM ONE's water leak port. When the two metal contacts are in a pool of water, it is detected by the device.
It can optionally be mounted to a surface using the two included screws.
You can also purchase this standalone for your own projects! Connect the red wire to a GPIO with a pull-up resistor to the positive voltage, and the black wire to ground. When water is detected, the output will be pulled low.
It supports 3-36V and comes with a JST XHP-2 connector.
