基于IOT的室内空气质量监测系统

AbstractWith the further modernization of production and lifestyle,people spend morethan 93%of their time in indoor activities.Although the concentration of indoor airpollution is often low,the accumulated exposure increases over a long period of time.The leakage of gas,natural gas,liquefied petroleum gas and other harmful gasescaused by misoperation or equipment fault in People's Daily life brings fatal harm topeople.Therefore,indoor air quality is more important to human health.This topic is through the STC89C51 microcontroller as the main controller isdesigned,the control of MQ-2 smoke sensor module ZE08 formaldehyde-CH20DHT11 temperature and humidity detection module and ADC0832 AD converter torealize to the concentration of harmful gas in the air for collection and analysis of thisdesign can achieve low power consumption high reliability accurately and effectivelyfor detecting harmful gas concentration in indoor environment and even thecharacteristics of the alarm to remind people to make effective measures when thechroma of harmful gas,can make more families to avoid disasterKey words:STC89C51;Mq-2 sensor;Temperature and humidity detectionFormaldehyde module ZE08-CH2O
