摘要
基于OceanConnect平台和Android操作系统,以STM32L431Rx单片机为主控制器,采用NBIOT技术建立了一种室内空气质量检测系统。该系统使用温湿度传感器DHT11、夏普光学灰尘传感器GP2Y1014AU0F、甲醛传感器ZE08-CH2O、一氧化碳传感器MQ-7完成对室内温湿度、PM2.5、甲醛、一氧化碳的检测,以空气净化器为远程控制的家电,来实现Android客户端实时监测室内空气质量和远程控制家电。实验证明,用户能通过Android客户端实时监控室内空气质量以及远程控制空气净化器;各传感器采集的数据与实际结果相近。该系统性能稳定可靠、操作简单、成本低廉,符合预期目标。
Based on OceanConnect platform and Android operating system,an indoor air quality detection system is established with STM32L431Rx MCU as the main controller and NB IOT technology.The system uses temperature and humidity sensor DHT11,Sharp optical dust sensor GP2Y1014AU0F,formaldehyde sensor ZE08 CH2O,carbon monoxide sensor MQ 7 to complete the detection of indoor temperature and humidity,PM2.5,formaldehyde and carbon monoxide.The air purifier is used as remote control household appliances to realize Android client real time monitoring of indoor air quality and remote control of household appliances.Experiments show that users can monitor indoor air quality in real time and control air purifier remotely through Android client,and the data collected by sensors are similar to the actual results.The system has stable and reliable performance,simple operation,low cost,and meets the expected goals.
