Sensors

Choose a sensor to collect data while your femtosat flies. Your sensor should provide valuable information about the rocket’s ascent and the femtosat’s descent. For example, it’s unlikely you could provide valuable information about the flight with a soil moisture sensor. We recommend the following sensors, because SparkFun.com has tutorials for them. If you choose a different sensor, make sure it outputs meaningful data and interfaces with your bus.

For practise we will provide breakout boards - pre-assembled boards used for testing - that you can check out and use in your development. For your actual femtosat you will solder on just the actual part to make sure it doesn’t take up too much space. You won’t have to purchase any of the materials online. Instead you can purchase them from the EE shop located on the 4th floor of the Clyde building.

Arduino Library Download: Can be downloaded from the github page or from the Spacecraft Club Public Files here.

Note: the library above is not the same as the one used in the demo of the hookup guide. We recommend the library in the link which is newer and better. It comes with several examples that you can use to help you in your programming.
