Design of Intelligent Monitoring System for Greenhouse

In order to solve the defects of traditional methods in measuring and adjusting the parameters of greenhouse environment, a micro controller-based automatic controlling system of temperature and humidity is designed in this paper. It introduced the hardware, software flow chart and the RS-485-based communications network. The slave machines are mainly responsible for collecting the data, displaying and sending it to the host computer, when the parameter exceeds the threshold, the fan will rotate at once and send alarming signals. The master machine received the data via RS-485 bus, saved the data to database and showed them in the form of curves. Experiments indicated that the system has good scalability, wide measuring range and strong anti-jamming features.
