PROMPT - Project for Recording, Observing, and Measuring Parachute Tube
The PROMPT is a remote sensor daughterboard that will be placed at the base of the parachute bay, to record metrics regarding the operation of the parachutes. The data from this module will be sent back to the main sensor board over RS485. This includes:
- The pressure of the parachute bay
- The temperature inside the parachute bay
- The temperature in the booster
- Whether or not the payload has been deployed
