摘　　要：随着我国经济的发展和信息技术的进步,工业污染日益严重,环境检测也成为人们关注的问题,家用环境测试仪需求量日益增加.本设计通过蓝牙通讯技术,利用手机检测CO、PM2.5、温度、湿度等参数.以STC89C52RC单片机为主控,采用相关传感器组建系统硬件电路.其中使用DHT11温湿度传感器完成对温度和湿度的采集,采用MQ-7一氧化碳传感器和GP2Y1014AU0F灰尘传感器分别检测CO和PM2.5浓度.利用单片机对当前采集的环境数据进行处理,通过LCD12864液晶模块显示相关数值,并利用HC-05蓝牙模块将传输采集的数据在手机上显示,实现了无线实时监控.本系统还可以通过按键设置数据阈值,一旦偏离正常范围就会发出声光警示,同时启动风扇进行空气流通循环.With the development of China’s economy and the progress of information technology, industrial pollution is becoming increasingly serious, environmental testing has become a concern, and the demand for household environmental testing instruments is also increasing. This design uses Bluetooth communication technology, through the use of mobile phones can detect CO, PM2.5, temperature, humidity and other parameters. The STC89 C52 RC microcontroller unit is used as the main control, and relevant sensors are used to build the system hardware circuit. Among them, DHT11 temperature and humidity sensor is used to collect temperature and humidity, MQ-7 carbon monoxide sensor and GP2 Y1014 AU0 F dust sensor are used to detect CO and PM2.5 concentration respectively. The microcontroller unit processes the current collected environmental data, displays the relevant values through LCD12864 liquid crystal module, and displays the collected data on the mobile phone by HC-05 Bluetooth module, which realizes the wireless real-time monitoring. The system can also set the data threshold by pressing the key, once it deviates from the normal range, it will send out sound and light warning, and start the fan for air circulation at the same time.
