This is a desktop prototype for a vacuum chamber being developed for the UTS Rocketry Team.
The aim for this desktop prototype is to develop and test a closed loop controller that is able to produce the pressure curve generated by Open Rocket simulations.
Eventually the software electronics developed from this prototype will be integrated onto the larger scale vacuum chamber based inside the UTS Rocketry Team's workshop, which will be used for testing avionics sensors and hardware used onboard high powered rockets.
Below is a diagram of the envisioned system setup for the larger, workshop based system:
Prototype 2.1 is running on the Arduino platform. It has currently demonstrated very basic altitude holding, being able to maintain a simulated altitude of ~200 meters inside the desktop chamber.
Libraries:
- Wire.h
- LiquidCrystal_I2C
- AdafruitBMP280
