Good measurements?

What are some good measurements to take in the upper atmosphere?· I've already got a temperature sensor, but I have a few pins left and enough memory to add some more.· Humidity would be one, but seems kind of boring.· Any good suggestions?
Thanks,
Dave

Do you have a Stamp Tester?

CO2 and ozone could be cool. Are there any reasonably cheap off-the-shelf sensors for those?
I considered pressure, but didn't want to shell out 20$ for a pressure sensor... anyone know a good source for cheap pressure sensors?
We have some upper air sondes that we send up and the new ones have GPS.
But otherwise they have humidity, pressure and temp.·
if you built an air tight housing with a balloon on one side (where an opening would have to be made).· Then put one of them flexisensors against the back of the balloon....as you go up in atmosphere, the pressure reduces which sucks the balloon in to the chamber.· This puts a force on those sensors which could be read.· Of course, this isn't linear (the more a balloon stretches the harder it is to stretch)....so you'd have to do some sort of calibration curve beforehand I think!· And to do that properly you'd need a REAL pressure sensor in a test capsule to compare to your made up jobby.
Anyhow...just a thought!
Really though, you're limited to only a few things up in the air....well, you could measure wind and direction...but that's pretty well wasted on the point that your 'rocket' (assuming that's what you're using) is moving anyhow!
Buy one of those keychain digital camera's ($30canadian) and connect her up to a 555timer and take some pics on the way up!!
