An autonomous solar weather station

By martinm, in Internet of Things and Measures, october 24,2013.

Do you recall the solar box? Actually, it has never worked well enough to be useful. Here at Yoctopuce, it has been renamed the NULL box. Ruthless, but not so far from reality.

You have most probably already read about the Pebble smart watch, which connects to your phone to let you know about new emails, text messages, incoming calls, etc. A year after the original announcement, Pebble has eventually published the SDK to create an active “Watch App” for this watch. We thought it would be fun and convenient to be able to control our environment directly from a watch.
