Solar-powered Temperature Logger with Electric Imp and ThingSpeak
[Marcus Olsson] from Slickstreamer created a solar-powered temperature logger using the Electric Imp Wi-Fi module to push data up to ThingSpeak to store and visualize the data collected by his sensors. Marcus provides a parts list and a how-to on his blog. The temperature sensor, solar panel, and solar charger are all readily available parts from Adafruit.
Looking over the code for the Electric Imp, it looks pretty easy to cross-clouds from the Imp to ThingSpeak. Check out the source code on GitHub and full details on Slickstreamer.
