[Marcus Olsson] of slickstreamer made a battery-powered temperature logger using ThingSpeak to store and visualize the data collected. He chose the Electric Imp Wi-Fi module for connectivity. The project is complete with a 3D printed case.
All of the source code to connect Electric Imp to ThingSpeak and the 3D printer design files are available on Marcus’ blog ‘slickstreamer‘.
[C.A.V.A.] created a cigar humidor with a social life. A humidor stores cigars in a humidity controlled environment to maintain freshness, but this special humidor sends the humidity sensor value to ThingSpeak and alerts Twitter when you need to add water. The project uses a humidity sensor and an Arduino Ethernet to post the data to the ThingSpeak API.
