温室大棚的问世对我国农业产业链的发展起到了显著的促进作用。随着信息自动化技术的不断拓新,对温室大棚的自动控制也显得尤为重要。本文采用AT89C51单片机为主芯片的监控系统,来对将温室大棚内的温度和湿度进行检测及控制。控制系统中的传感器采用DHT11,通过它对外界的温度和湿度进行采集,并采用模块化设计,将检测结果通过1602液晶屏显示出来。同时采用越限声光报警随即启动外部设备,最终得到适宜的环境,保证大棚内的蔬菜生长在优质舒适的环境内以顺应生产需要。
The advent of greenhouse on the development of China’s agricultural industry chain has played a significant role in promoting. With the constant development of information automation technology, automatic control of greenhouse is also very important. In this paper, AT89C51 microcontroller-based chip monitoring system, to the greenhouse temperature and humidity to detect and control. The sensor in the control system adopts DHT11, through which the temperature and humidity of the outside world are collected, and the modular design is adopted to display the test result through the 1602 LCD screen. At the same time with the more limit sound and light alarm immediately start the external equipment, and ultimately get the right environment to ensure that the greenhouse vegetables grow in a good quality and comfortable environment to meet the production needs.
