Running on Rays of Light and Off-the-Shelf Hardware
We have previously looked at how to make a wireless device live for years on one tiny coin cell battery. This time we up the game and make it live forever, using solar power and off-the-shelf hardware.
We build a prototype of our device and go through the technical details involved in designing for solar power. We use off-the-shelf hardware running the latest version of the Thingsquare ultra low-power software. Light does not provide a lot of power, so we need software that can make the most of it.
