This is the current setup of my Raspberry Pi. The white band connects the camera, and the smaller blue block is the temperature sensor.
My next big task is to get a pressure sensor. Just doing some quick browsing, I found this one:
It looks like it is simple to use, just like the temperature sensor. Then I can just use the hydrostatic equation to translate pressure into height:
My brother also suggested another option some time ago:
Another option is to use a GPS:
Slightly more expensive, but also a good option.
Either way, my decision is based on this question: How do I get the equipment to disconnect from the balloon once it reaches 2km?
