Hi Guys,
I'm thinking about hacking a simple solar powered garden light to power my Arduino based sensor array. The light has a single AAA battery that provides 600mA and 1.28V (tested values). The solar panel provides 1.15v (tested value based on indoor light).
Ultimately I am looking to power an Arduino micro (3.3v) about 3 times a day for roughly 2 minutes a pop to transmit temperature and moisture/humidity data. The fact that the battery provides 600mA was very interesting as that is ample power for this setup, and to boot there is ample space in the light body to hide my Arduino and sensors.
The low voltage was my greatest concern, rather than using a boost converter I was thinking of putting three AAA batteries (in series) in there but I would need a new charge controller. Can anyone recommend an IC that would be able to take a 1v input and charge these three 1.2v batteries?
If anyone has built anything similar I'd love advice on the build.
Thanks!,
Peter
