Electronic plant water alarm
Product information:
This smart soil sensor keeps an eye on whether a plant needs water by continuously measuring the soil moisture.
If the humidity drops below the set level, the sensor will make a chirping sound (only when it is light) to indicate that the plant needs water.
The 6-pin AVR header also allows you to program the sensor yourself and provide it with other functions, if desired.
Operates on a CR2032 button cell battery (not included).
