智能温湿度控制仪的设计与实现

The Design and Implementation of the Intelligent Temperature and Humidity Controller

本智能温湿度控制仪核心器件是STC90C516RD+单片机,利用机械按键来设定需要控制温湿度的范围,采用DHT11来采集外界实际的温湿度,并送给微处理器,微处理器经过数据处理并与理论值进行对比,若超出范围,让继电器来控制加湿器、加热器、抽湿器或制冷器的工作,从而改变当前环境温湿度值达到预期值,并将采集的结果通过LCD1602液晶显示器显示出来。

The core device of the intelligent temperature and humidity controller was the STC90C516RD+single chip microcomputer which used the mechanical keystrokes to set the range of temperature and humidity,the DHT11 was used to collect the actual temperature and humidity of the environment and sent it to the microprocessor.After date processing,compare microprocessor with the theoretical value.If it was out of range,let the relays control the work of the humidifier,heater,dehumidifier or chiller so as to change the current ambient temperature and humidity value to the expected value and display the collected results on the LCD1602.
