Hi Paul,
Do I understand you to mean that a cell phone camera could be used to remot=
ely monitor a thermometer? Could you call it up and get a real time image? =
How would that be done? I'm a little behind on cell phone technology. Thank=
s for any more details.

Brian,

The term you're probably looking for is Radiosonde.
Here's a description: Radiosondes

There are a few old surplus sondes available on eBay. Do worry about the c=
ondition of the batteries on those. Acquiring/borrowing/running a receiver=
for such a sonde is a little more tricky.

The quick class projects discussed have just used a cell phone camera and h=
ave relied on recovery of the balloon to get any data. Depending on launch=
conditions, your balloon may end up 80 miles downrange. Point your camera=
at a thermometer?

Idea: Has anyone ever seen a small bluetooth weather station?

Here's a fun way to find your balloon once it's down:
Global GPS Tracker with Two Way Calling + SMS Alerts

It would be really nice if you could figure out a way to do this with a cel=
lphone-based GPS package tracking system. Here's one that tracks temperatu=
re in real time:
CoolTrax - Coolchain Monitoring and Tracking Temperature and GPS, Thermo Ki=
ng and Carrier Reefer Monitoring
These are designed for a very different purpose. But it could be the right=
technology to replace the old radiosonde system.
