Supervisory Control System For Environmental Parameters in Greenhouse : LAP Lambert Academic Publishing : 9786137332351 : 6137332357 : 09 Mar 2021 : For the environmental parameters monitoring requirements in greenhouse, a wireless measurement and control system for temperature and humidity is developed. It overcomes the disadvantages of wired monitoring system, such as complicated wiring, and difficult maintenance. The environmental parameters in every greenhouse were measured and controlled by micro-controller. The hardware and software of the monitoring system are discussed in detail. The experimental results show that the developed monitoring system has the following features, such as simple structure, high reliability, good extensible and flexible configuration. It can control and adjust automatically the environmental parameters in every greenhouse, and has project practicality and vendibility.
