基于单片机的无限报警系统

AbstractThe wireless alarm system discussed in this study uses STC89C52 as the core anduses basic modules such as digital-to-analog converters,temperature sensors,smokesensors,and relays.Through the above-mentioned module sensors,the disasterprevention in the family is prevented in advance,so an alarm system is designed basedon the single-chip microcomputer,which has a high cost performance and can be easilyinstalled.This alarm system can perform smoke detection and temperature detection.When the measured value deviates from the specified range,an alarm will be issued anda text message will be sent to the owner.If the temperature and flammable gasconcentration change,the system will also make corresponding judgments andtreatments and issue an alarm signal.The relay realizes the load control and the GSMmodule short message prompt,so as to realize wireless alarm and intelligent prompt toensure the safety of the living environment.Keywords:Wireless Alarm System;STC89C52;DS18B20;GSM
