摘 要:本次的方案是利用STC89C52单片机为主控制器设计了一个大棚温湿度控制器,对大棚内植物生长环境进行监测和简单控制。其中利用DHT11传感器实时采集温湿度值并传送给单片机,经过单片机的处理再准确无误的显示在LCD1602上,假如实际温湿度超出了设定值,则LED报警灯亮,驱动负载调节温湿度使大棚内的温湿度恒定。39350 毕业论文关键词:监测;1602液晶显示;主控制器;智能控制
The Design of Control System of Temperature and Humidity in Greenhouse Based on MCU
Abstract:The solution is to use STC89C52 microcontroller as the core design of a greenhouse temperature and humidity control system in greenhouse, plant growth environment monitoring and simple control. The use of DHT11 digital temperature and humidity sensor to collect temperature and humidity and transmitted to the microcontroller through the single-chip processing and correct display on the LCD1602, if the actual temperature and humidity exceeds the set value, the LED warning lights, the relay to drive the corresponding load to regulate temperatureand humidity.
