chri721u 0:a5831f680465 6 Brief description:
chri721u 0:a5831f680465 7 Microcontroller observing the climate within a greenhouse, and displaying warnings/information as needed.
chri721u 0:a5831f680465 8 Sensors monitor light levels, as well as temperature and humidity.
chri721u 0:a5831f680465 9 To simulate an actual greenhouse, LEDs will be used in place of actual influences.
chri721u 0:a5831f680465 10
chri721u 0:a5831f680465 11 Objectives:
chri721u 0:a5831f680465 12 - Able to set controller location (Which section/greenhouse is it located in)
chri721u 0:a5831f680465 13 - Able to open window at certain temperature tresholds (For 5 minutes)
chri721u 0:a5831f680465 14 - Water plants at regular intervals (Twice a day)
chri721u 0:a5831f680465 15 - Plants must have light for at least 12 hours. If weather is cloudy, artificial lights.
chri721u 0:a5831f680465 16 - Testmode: Alternate time-tracking system, much faster than 24 hour system.
