However, the greenhouse temperature and humidity requirements for a series of air composition indicators are very strict, and greenhouse modernization must have a set of temperature and humidity measurement and control system, the design is for people living with and the continuous improvement of production level, to the living environment and the requirements of the production environment is particularly important, control temperature and humidity is a typical example, therefore, emerge as the times require an intelligent temperature and humidity detection system in modern life and fast, convenient and reliable detection system, especially in the industrial production if the detection of inaccurate will occur in many production accidents. To provide a better life for modern people to work, scientific research, and more convenient facilities, we must start from the SCM technology, all toward digital control system, intelligent control direction. The design is based on single-chip microcomputer as the core, with the temperature and humidity sensor, detecting system and related peripheral circuit, can receive the measurement of environmental temperature and humidity signal, detecting personnel can be displayed by the LCD data, the temperature and humidity of real-time monitoring of the environment. The measurement operation all can be realized through the host computer control software, the measurement signals are temperature and humidity sensor, the circuit is con
