Terrace Rain Alert
A rain sensor on the terrace catches the first drops and your phone beeps, so the clothes come in dry.
Kids OK, with an adult
DIY project. Children must build this only with an adult (16+ years) beside them at all times. Not suitable for children under 8 years.

The video link will be added here soon.
How it works
- Water on the rain plate connects its tracks.
- The LM393 board turns that into a clean digital signal on DO.
- The ESP32 sounds the buzzer at home.
- It also sends a phone alert.
