Temperature in my Classroom

I thought it would be neat to see how hot it gets each day in my class.  I hooked an Netduino up to an DHT22 temperature and humidity sensor, and linked them online through COSM.com  What you see is the graphs for temperature and humidity in my room.

Yes, the temperature gets to 90 almost every day.  The humidity, for some reason, is very low.  Weird.  Share if you like it, or maybe pitch in for air conditioning for us :)
