基于STC12C5A60S2单片机互联感知的室内环境监测 贱人 摘要：如今人们在室内花费了大量的时间，而室内环境质量与人体健康息息相关，因此室内环境气体质量检测至关重要。针对目前市场上室内气体检测仪成本高、精度低、检测种类单一等缺点，本文基于物联网传感平台，以单片机为控制核心，设计出一种室内环境气体实时检测系统。本系统立足于解决室内污染超标而不被人所知继而危害人体健康的问题，实现对室内环境气体质量的实时动态检测，根据传感器反馈的数据，结合最高危害上限指标要求，及时给出室内环境污染对人体健康危害的报警基点。利用CO传感器、CO2传感器、甲醛传感器、温湿度传感器等实时检测室内环境气体质量，将检测数据交给单片机分析处理，单片机可根据检测值自动做出是否报警的决定。 关键词：室内环境检测；物联网；单片机；声光报警； 传感器 The indoor environment testing system based on IOT sensor design Li Cheng (North University of China branch in Shuo Zhou Shang Xi，036000) Abstract: Nowadays people spend much of their time indoors, and indoor environmental quality is closely related to human health, so the indoor environment gas detection is very important. Aiming at the defects of the market at present high cost of indoor gas detector, low precision, detection of single species, this paper based on the Internet of things, with single chip microcomputer as the control core design an indoor environment gas real-time detection system. This system is based on the solution to indoor pollution exceeds bid without being known and endanger human body health problems, realize real-time dynamic detection of the indoor environmental air quality, according to the feedback sensor data, Combined with the highest hazard limit index requirements, timely give alarm points of indoor environment pollution on human health hazards. The CO sensor, CO2 sensor, formaldehyde sensor, temperature and humidity sensor real-time detection of indoor air quality and the detection data to the microcontroller processing, the MCU can according to the detected values to make decision whether to give an alarm automatically.
