摘 要:本装置可以保证对室内环境的湿度和温度以及部分可燃气体的浓度进行自动的检测,同时满足对室内的环境的变量进行详尽、实时、长时期监测的要求。装置由单片机控制,使用的元件有温度传感器,湿度传感器以及气敏传感器。把测量元件和单片机相连接,收集到的数据及时存储并且经过处理后显示到LCD屏。该装置还要具备超限报警功能。该设计对室内温湿度实现了检测与显示,而对CO和甲烷等有害气体完成超标报警,为人们的生活、娱乐及公共场所的环境提供了一种有效的防护系统。34253 毕业论文关键词:STC89C52;SHT11;监测;MQ211;室内环境
Design indoor environment monitoring device
Abstract: The device ensures indoor environment humidity and temperature and the concentration of combustible gas portion for the automatic detection, while meeting the indoor environment variable detailed, real-time, long time monitoring. Means controlled by a microcontroller, components used are temperature sensors, humidity sensors and gas sensors. The measuring cell is connected to the microcontroller, the collected data is stored and treated and promptly displayed on the LCD screen. The device also includes a limit alarm function.
