PROMPT - Project for Recording, Observing, and Measuring Parachute Tube

• 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

Temperature Sensing

Since this board needs to monitor 2 remote temperature sensors, choosing a relatively low-cost and compact temperature sensing solution is important. Thermistors are immediately out of the running since the motor's temperature can reach up to 212C, far beyond the range of most NTCs. So, a choice is left between RTDs and Thermocouples. While RTDs would be more accurate, they are more expensive and available in fewer packages than a thermocouple would be.
