Moisture monitoring

Creation of a simple device with Arduino NANO for soil moisture monitoring, enabling connection to other devices such as water pump, replace the battery with a solar panel or even adding wifi/GSM modules for communication between the “plant” with the internet (sending twitters, emails, etc.).

The LED has the following configuration:
- Red for humidity below 20%
- Green humidity equal to or above 20% and below 80%
- Blue for humidity equal to or above 80% (soaked)
