Project: Icarus
A model rocketry project studying temperatures inside the body tube
... on the temperature between the motor mount and the body tube, the temperature above the motor mount but below the flameproof recovery wadding, and finally the area where the parachute is housed, just above the wadding.
This project is used in conjunction with the Arduino Primary Avionics Module (A-PAM) which can be found at https://sourceforge.net/projects/arduino-base-avionics-bay.
