摘要
系统使用DHT11传感器作为空气温湿度测量模块,首先由DHT11温湿度传感器把采集到的温湿度数据传给单片机STC89C52,经过单片机的处理,传送到液晶显示屏1602进行准确的显示。同时,如果温湿度超过设定的阀值,继电器将会驱动风扇工作。经反复试验测试,系统稳定性高,可广泛用于仓库等场合。
The system used DHT11 sensor as the temperature and humidity measurement module,first the temperature and humidity sensor DHT11 collected the temperature and humidity data,it was transmitted to the SCM(Single Chip Microcomputer)STC89C52, transferred to the liquid crystal display 1602 accurately display through the SCM processed. At the same time, if the temperature and humidity exceeded the threshold, the relay would drived fan. After repeat tested, the system has the advantages of high stability, Can be widely used in warehouse, etc.
