The thingSoC Water Sensor is a simple passive water detector board that is used to sense the presence of water in an area (i.e. your basement) or a container (pet watering bowl). Depending on whether you use positive logic (water present) or negative logic (water absent), you can use the second connector to activate a relay to pump water out (of your basement) or in (to your pet's water bowl).
It 's a very simple design, alternating strips of circuit board are connected to sensor elements and to ground. When water is present the level of the sensor will change from high (pulled up by a one million ohm resistor) to low.
The connectors are compatible with the Seeedstudio Grove System , and will work with most microprocessor systems. Example programs for the Arduino IDE are included in the Examples section of the Github repository
