Study on Computer Monitoring and ControllingSystem for Greenhouse Environment

摘要

In this paper, we introduce a computer monitoring and controlling system forgreenhouse environment. The system adopts sensor technology, automatic checkingtechnology, communication technology and microcomputer technology, realizes the monitoringand controlling of environmental parameters, including temperature, humidity, light intensity andco2 density. Its hardware consists of data collecting circuits, controllers, displaying circuits and apc. The hard core of the controller is a 80C196KB microprocessor, which collects, saves,preprocess the environment parameters. The pc is the center of the system. It finishes theunified management of greenhouse by way of serial port, which connects with themicroprocessor in every greenhouse. The whole system is easy to operate and expand.
