摘　　要：设计以AT89C51为控制核心,采用DHT11传感器对实验室的湿度、温度进行采集,采用MQ-2气敏传感器进行了实验室内有害气体的浓度检测,CO、火灾烟雾等有害气体的泄漏检测,并由LM041L液晶显示器实时显示,当检测到的数据超限时进行报警处理。同时,通过Proteus仿真软件对系统做了功能测试及仿真。The design uses the AT89C51 MCU as the control center,realizes the humidity and temperature data acquisition through the temperature and humidity sensor DHT11;the MQ-2 gas sensor is used to detect the concentration of harmful gases in the laboratory to prevent the leakage of CO,fire smoke and other harmful gases.At the same time,they are displayed on the LM041L real-time.When the detection data exceeds the limit,the alarm is given.The system is simulated and tested by the simulation software proteus.
