摘　　要：本文以STC90C52单片机为核心,通过MQ-2烟雾传感器采集室内烟雾浓度值,通过DS18B20数字温度传感器采集室内温度值,并将烟雾浓度值和温度值传送到LCD1602显示器上进行显示。当烟雾浓度值、温度大于设定的阈值时,会启动蜂鸣器发出报警;当单片机收到上位机主控制器传送数据指令时,能将当前采集的烟雾浓度值和温度值通过单片机串行口传送给上位机主控制器。This paper takes stc90c52 single chip microcomputer as the core,collects the indoor smoke concentration value through mq-2 smoke sensor,collects the indoor temperature value through DS18B20 digital temperature sensor,and transmits the smoke concentration value and temperature value to LCD1602 display for display.When the smoke concentration and temperature are greater than the set threshold,the buzzer will be started to give an alarm;When the single chip microcomputer receives the data command transmitted by the main controller of the upper computer,it can transmit the currently collected smoke concentration value and temperature value to the main controller of the upper computer through the serial port of the single chip microcomputer.
