This is a water alarm for my Air Conditioner’s 15 liters water collector canister that is needed to be manually emptied from time to time. Code can also be used as a flooding alarm system. This code checks for water every 30 seconds and turns on a led and a virtual led when water is detected. It also sends a push+email notification every 8 hours as long as water is detected.
Suggestions for improvements are welcome. Enjoy /Stefan @ stockholmviews.com
