This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.

Based on dual BMP280 pressure sensors and a KY-013, water, temperature sensor this project is intended for monitoring evaporative and decorative ponds, creeks or wells. The functionality could also ...
