The Green Detect project was a great challenge for me, especially for the solutions I implemented to reduce consumption and allow the energy independence of each individual module.
That's why I decided to subscribe the project to Low-Power challenge.

All 6 actions that I implemented to reduce consumption are described in detail in the following log:

Consumption reduction

The solutions that I have adopted at the software level to synchronize the modules in communication and deep sleep management have also been fundamental.
They are described in this log:  Timing and synchrony with self adapting deep sleep time

In this Log I describe the charger circuit:  Solar charger circuit
