A water leak can often be a warning of imminent catastrophic failure with many appliances such as a washing machine or dishwasher. With this simple water detection system not only could you quickly detect appliance faults, but you could also set the system up to notify you if it is raining and you have left washing on the line. The possibilities are endless. This project uses a Particle Photon, although it could work with any microcontroller, and exploits the conducting properties of water to easily detect when water is present somewhere it shouldn’t be!
