How hot is it?

Like other hackerspaces I’m finding, we have less than optimal heating and cooling. This summer, a popular complaint was that our space was too hot. We had thermometers, but you can’t read them from your appartment before you head down to the shop. Last winter, we had the same problem with the shop being too cold for happy hacking.
NOT ANY MORE! Harnessing a spare arduino and a few DS18B20+ I’ve finally built a network attached thermometer.

Using example code found online, the arduino is polling both DS18B20+s periodically and spitting the current temperatures to the serial port. A perl script is catching this and saving the results to a database with rrdtool. You can see the current temperature graphs on our camera page.
