摘要
为满足人们对室内居住环境的更高要求,设计了一套基于STC89C52单片机的室内空气质量监测系统。传感器硬件方面采用了GP2Y1010AU0F粉尘传感器和DHT11温湿度传感器,以完成对各项空气指标的监测,并结合液晶显示、按键输入、声光报警等模块进行辅助;软件设计主要包括对各模块的初始化及逻辑实现。测试结果证明,该空气质量监测系统可以对PM2.5以及温湿度实行有效的监测和报警,并具有体积小、能耗低、使用便捷等优点。
In order to meet the people's higher requirements for indoor living environment,an indoor air monitoring system was designed mainly based on the STC89C52 MCU.The sensor hardware adopted the GP2Y1010AU0F dust sensor and DHT11 temperature and humidity sensor to complete the monitoring of various air indicators,combined with LCD display,key input and alarm module.The software design mainly includes the initialization and logic realization of each module.The test results prove that the air quality monitoring system can effectively monitor and alarm PM2.5,temperature,and humidity,and has the advantages of a small size,low energy consumption,easy use,etc.
