The sensors that they offer are rather... quirky....
http://www.kickstarter.com/projects/575 ... t-in-space
A temp sensor will only measure the temp of the sensor board. Without an atmosphere, there's no thermal conductivity for the sensor to get to "ambient" temperature.
The barometric sensor that is illustrated is good for 30-110kPa. "ambient" pressure in the satellite doesn't fall into that range.
The GPS sensor won't function at that altitude due to wassenaar GPS restrictions.
Ozone and CO2 sensor - ummm.... yeah....
The only really useful sensor would be the camera. Unfortunately, an 8 bit AVR is a little bit underpowered for any image processing.

| Best data collection would be the telemetry during reentry. |

Wow, what an interesting project.
The AVR only has to capture the images and save them to an SD card, as the Satellite will then dump the data to
Earth via a Hamsat.
I wonder if they have tested the device over the temperature range of interest?

Those experimentation boards are definitely not going to survive the launch forces 
And how do you rad hard this stuff? |

| Now they want $75K to build a bigger sat. I want a piece of that vaporware. |
