I'd like to build a water leak detection mechanism, and put a sensor under the dishwasher and a sensor under the kitchen sink, and notify if there's moisture detected. Any thoughts on the best way to do that? Three options in the tutorial section on the site:
- Soil moisture sensor (not applicable)
- Rain sensor
- Water level sensor
The rain sensor, I assume, needs actual droplets on the face of it; so unless the leak happens right on top of the board, it won't trigger anything. The water level sensor seems very similar. So - any ideas on a better approach? Humidity might be a good option... or using a rain sensor but placing paper or other wicking material over the entire area to wick moisture towards the sensor?
