基于AT89C51的温室大棚环境参数自动控制系统的设计

Design of Automatic Control System for Greenhouse Environment Parameters Based on Single Chip Microcomputer

针对温室大棚的环境参数,运用AT89C51单片机和AM2301传感器设计了一款监控系统,通过该款自动控制系统可以精确检测到温室大棚内的温度和湿度是否符合要求。首先,根据温室大棚的实际需要设定一个标准的温室范围,然后AM2301传感器将采集的温度和湿度信息传递给AT89C51单片机,最后,单片机经过一系列的运算处理将数值在1602液晶屏上显示出来,同时会将该数值和之前设置的标准温湿度范围进行比较,一旦发现检测到的数值超出设定的范围,系统便会发出报警。

Based on the environment parameters of the greenhouse, this paper designs a monitoring system using AT89C51 microcontroller and AM2301 sensor. The automatic control system can accurately detect whether the greenhouse temperature and humidity can meet the requirements. A standard range of greenhouse is set based on the actual needs. Then AM2301 sensors transmit the collected temperature and humidity information to AT89C51 microcontroller. At last, LCD 1602 displays the processed value which will be compared with previous standard temperature and humidity range. Once the detected value exceeds the set range, the system will alarm.
