As we all know, greenhouse creates an optimal growth environment for plants with manual control. The temperature and humidity is crucial for plant growth. Otherwise, it would affect the plants health and decrease the plant production, thereby impairing the farm revenue.

• In spring and summer, when greenhouse is overheated, soil is tend to evaporate the moisture and then plants couldn’t absorb the enough moisture for further growth. Finally, plants would die.
• Of course, plants wouldn’t grow well at too low temperature so administrators need to inspect the greenhouse condition over and over again during the cold season, which is a troublesome and low-efficiency task. Moreover, it is unavoidable that administrator forgets to check it or is too busy to check it.
• Like circulation fans, exhaust fans and vents, those greenhouse facilities maintain the proper growth environment. If these facilities don’t function well, it would cause temperature change and then threaten plant growth.
