The destruction of water will soon make even the most beautiful buildings impossible to survive. [Andres Leon] has encountered a small flood of air conditioning units and hopes to avoid such problems in the future. So he built a wireless monitor to solve this problem.
The device is based on ESP8266, allowing it to communicate wirelessly with the home assistant. Therefore, if it detects water through the anti rust probe, it can notify Home Assistant through MQTT message. There, the family assistant can notify the owner remotely by phone and email. In addition, for the sake of completeness, there is also a loud buzzer in the device. When water is detected, the buzzer will also sound. As the ship is equipped with 2500 mAh lithium polymer battery, the device can run for up to 5 months between two charges.
When you go out for a long time, it is particularly useful to integrate the alarm system into the smart home system. When we are not paying attention, things like water leakage will cause damage over time, so any IoT equipment that can help in this regard is useful. If you want to investigate the cause of a difficult leak, this other project may help. Video after break.
