Product overview
This practical module can sense the presence of water. It is contactless because there is no
sensing element that makes physical contact with the water. The sensor is even able to detect the
presence of water through small thicknesses of plastic, glass, ceramic, and other non-metallic
materials.
The sensor features a built-in red indicator LED that lights up when water is detected and the
detection signal will output a high signal when water is present. The polarity of the detection signal
can be changed by grounding the black wire, which will change the detection signal type to an
active low signal. The sensor's sensitivity can be adjusted by opening the top cover and turning the
blue potentiometer.
