Greenhouse sensor software working

The software for measuring temperature, light and battery voltage is working for the mica motes.

The motes read the three sensors and send the results over the air to a base-station running a Java program which receives the data. Below is some example output, I stuck mt thumb over the light sensor to get the reading to change. Unfortunately checking the temperature sensor is not quite so easy, I am open to suggestions for how to get it to change (quickly - for testing). Since they turned the radiators off I have been using a kettle. All suggestions from the guys at Uni so far revolve around sticking the mote in places where I don’t think it wants to go!

All measurements are in millivolts.
