But each grower knows that the sunlight can not be controlled. Artificial daylight in horticulture are more and more recognized as artificial sunlight can control the plant growth season and thoroughly to shorten the time of plant growth. Plant growth lights is not sufficient natural light to supplement light. The process of using is a combination of illumination time and strength characteristics of the fill light control. Long-day crop in accordance with its sunshine demand, more than according to the short day crops less according to plant growth light control. Natural light can basically meet the plant itself, the light needs, without irradiation, the light intensity weakened, fill light, that is, light controls plant growth lamps. Rational use of plant growth lamps, can effectively increase economic efficiency. This design is microcontroller technology Led Plant Grow Light photoelectric control, timing control, circuit design part of the main control circuit is the combination of single-chip design. The control circuit part of the analysis and discussion of the various parts of the circuit theory, control strategy, according to the requirements of light and timing control to determine growth lights lit on and off.
