I'm teaching 15 Idaho teachers how to make and use BalloonSats. The class is called iSTEM and for the class, I am creating BalloonSat kits. These kits contain all the electronics and tools to make a BalloonSat from scratch. Each BalloonSat will have three sensors to choose from, a camera, two temperature sensor array, and a temperature and relative humidity sensor array.
With a little more funding, I can also add a LED photometer array, and a temperature and pressure array.
It takes a lot of stuff to make a fleet of BalloonSats.
