智能家居监控终端设计

苏州科技大学本科生毕业设计（论文）Intelligent home monitoring terminal designAbstractThis design is mainly aimed at intelligent home monitoring,which mainlymonitors the indoor environment,including temperature humidity detection and COdetection,PM2.5 detection and GSM module.In the temperature and humiditydetection part,we use the temperature and humidity sensor DHTI1,which can reducethe measurement error,and at the same time,the excellent cost of anti-interferenceability is relatively low.CO detection part,we use the gas sensor MQ-7 andADC0832 AD converter,through these modules,we can effectively detect the indoorCO concentration,when there is a fire,through its detected data we can understandthe indoor and the concentration of toxic gases,at the same time the system will senda corresponding sound and light alarm according to the data so as to realize the earlywarning of fire.In the PM2.5 detection part,we use the dust sensor GP2Y1010AU,and the detection room will judge the dust concentration according to the pre-setvalue,so as to realize the monitoring.GSM module part,we use SIM900A module,when the sensors detect the indoor environment problems,they will transmit signal tothe SCM,SCM again after the signal processing,it will control the GSM module sendalarm information to cell phones,at the same time control buzzer and LED lights emitalarm information,thus to family environment monitoring.The project finished thefinal expectation,and finally reached the design requirements after debugging andtesting.Keywords Smart home;Single chip microcomputer;Anti-theft monitoring;GSM2
