This paper elaborates the control of environmental factors in the modern industry and agriculture, and according to the problem that the temperature and the humidity is hard to control automatically, this paper puts forward the design of the greenhouse automatic control system based on MSP430 single chip microcomputer. This design mainly introduces the overall design scheme of the automatic control system, and the use of the properties of various hardware based on MPS430, which mainly include temperature transmission sensor DS18B20 and the humidity transmission sensor CHR01. And then use the environmental control factor algorithm and numerical conversion fuzzy algorithm, so as to realize the temperature and humidity control system.
