Chamber Temperature Control System - Heating

Miniature Greenhouses for Precision Agriculture – DEC1617

Temperature Range: 21°C - 45°C. Arduino Logic:

  • User sets temperature
  • Calculate average temperature from 4

thermistors

  • Set space heater ON if:
  • Average temp < Set Temp
  • Set release fan ON and space heater OFF if:

○

Average temp > Set Temp

○

Temperature accuracy: +/- 1.8°C
