Solar - Temperature, Humidiy & Pressure board with charge monitoring
-
I was not able to resist the new ceech board the and the lucky one to receive the fully populated samples last week.
The board incorporates the hardware to solar charge a li-ion cell including the measurements for voltage & current of both solar and cell.
To test the board I dismantled a cheap solar garden light and connected a CR123 li-ion cell.
The result
For testing purposed I found that it works well to connect a HC-05 bluetooth module and use a mobile phone with bluetooth terminal to read the serial port. This way I don't need to carry a PC around the house. You can see the board producing it's intelligence
and the sketch which is communicating with the MySensors network

The HC-05 is a great idea. Thanks for sharing.
