Wireless XBee temperature sensor
XBee is one cool chip. I never worked with them so I didn't know that you could configure it to periodically read and send an analog readout of some of it's analog input pins. This way if you need to make some analog measurements you don't need an additional microcontroller, just good old XBee.
This project is a remote temperature sensor with LM34 temperature sensor and XBee at one side (the transmitter) and an Arduino with XBee and LED display to receive, parse and display the temperature value. Cool stuff!
