基于嵌入式智能家居防火防盗智能GSM短信报警系统

AbstractWith the high quality of life brought about by economic development,thevast majority of people pay more and more attention to their own property andhome security.They hope to use advanced technology to protect their ownproperty and home security more scientifically and reliably.Smart home alarmsThe system can minimize losses such as theft,robbery and fire,and better solveemergencies.The smart home alarm device studied in this topic uses STC89C52 as themain control chip to control other circuits,combined with external gas sensorMQ-2,infrared human pyroelectric sensor,DS18B20 temperature sensor torealize the perception of the peripheral environment,and the use of ADC0832 A/D converter,GSM module short message,sound and light alarm circuit realize theinteraction of internal information and external information.Finally,the controlprogram written in C language is combined with each module to complete thesensitive perception of environmental smoke,temperature and infrared to realizefire alarm and intelligent prompt..Key words:GSM MQ-2 gas sensor ire alarm MCU intelligent control
