摘要
采用AT89S52单片机和SHT11数字温湿度传感器构成成本低廉的温湿度监测系统。由AT89S52单片机将采集到的数据处理后发送到1602液晶显示器显示,同时当温度或湿度超过设定的上限或下限值时由发光二极管与蜂鸣器产生声光报警。系统结构简单、成本低廉、抗干扰能力强、适用范围广、功耗较低,符合仪器仪表小型化的潮流,为智能化的微型温湿度监测系统的开发与研究奠定了良好的基础。
The AT89S52MCU and SHT11digital temperature?humidity sensor are used to construct a temperature?humiditymonitoring system with low cost.The data acquired and processed by52?MCU is sent to LCD1602for displaying.If the value oftemperature or humidity exceeds the set valves,the sound and light alarms are generated by LED and buzzer.The system hassimple structure,low cost,strong anti?interference ability,wide application range and low power consumption,and conforms tothe trend of the instrument miniaturization,which lays the good foundations for the research and development of the intelligentmicro temperature?humidity monitoring system.
