摘要：In general, the greenhouse is a building that the whole room is made of eitherglass walls or roof. This is done to absorb incoming sunlight directly into theroom. Sunlight is used by plants in photosynthesis (the process of disposal thenecessary leaf chlorophyll in plants). But often times the temperature in theroom is too high due to greenhouse trapped heat inside the greenhouse and causethe greenhouse effect. This fan controller uses a temperature sensor, which willwork according to temperature changes received by the sensor temperature. Thatway when the temperature inside the greenhouse reached 28 ° C conditions, thisfan controller will work. Then at temperatures less than 28 ° C, fan controllerswill stop work. This tool is used as a method of protection against the survivalof plants in greenhouses is the prevention of the occurrence of too hightemperature in the greenhouse by using a fan.
