Abstract
The control of heat exchange is vital for plant life in off-world, low pressure,
greenhouses. The ability to control this process was limited by methodology and
technology. Mathematical models, based on classical mechanics are created to enhance
our control capabilities. Data is collected using various sensors placed inside the Low
Pressure Test Bed (LPTB) Chamber at Kennedy Space Center. Data from those sensors
became non-linear at various pressures below 25 kPa. We introduced mathematical
calibration corrections and found that sensor data linearity could be extended to a greater
range of pressures. These calibration corrections allow for sensor calibration corrections
in operational environments that differ from the environment of calibration (normal Earth
atmospheric pressure).
