基于AT89C52的农业温湿度智能控制系统设计

设计了农业温湿度智能控制系统,该系统采用DHT11温湿度传感器作为温湿度采集模块,单片机选用AT89C52代替并调用Virtual terminal模拟串口通信,LCD1604液晶显示器实时显示温湿度,实现了温湿度的测量、显示,可自动控制加热、降温、加湿、通风,实现温湿度控制以及超限报警处理,并利用Proteus与Keil进行实际电路的仿真。试验表明,该系统实现了可靠的温湿度监控。

We described the design of an intelligent control system of agriculture temperature and humidity.The system uses DHT11 temperature and humidity sensor as the temperature and humidity acquisition module.The SCM adopts AT89C52 to replace and call the virtual terminal for simulating serial communication.LCD1604 displays temperature and humidity in real time,which implements the measurement and display of temperature and humidity.The system is able to automatically control heating,cooling,humidification and ventilation,to achieve temperature and humidity control and over-limit alarm processing.The system also uses Proteus and Keil for actual circuit simulation.The experiment shows that the system is capable of reliable temperature and humidity monitoring.
