New environment parameters monitoring and control system for greenhouse based on master-slave distributed

According to the actual need of monitoring and control of greenhouse environment parameters in rural areas, a master-slave distributed measurement and control system is designed, in which PC is taken as the host. The system consists of PC, soil moisture measurement and control module, temperature and humidity, and CO₂ monitoring and control module. In the system, PC has large amount of data storage which is easy to make use of fuzzy control expert system, configuration software-KingView is used to develop software for PC, by which the development cycle is shorten and a friendly human-computer interaction is provided. Each monitoring and control module consists of STC12 series of microcontrollers, sensors, relays etc. Different modules are select based on the need of system to achieve control of greenhouse in partition and block.
