摘　　要：本设计是基于单片机的室内环境多参数监测系统。采用DHT11传感器实现对温度、湿度的检测。采用MQ-2传感器进行CO、CO2、甲醛、火灾烟雾等有害气体的泄漏检测,将模拟量转换成数字量由单片机AT89C51进行数据的分析处理并显示,当检测的信号超限时进行报警提示。This design is a multi-parameter monitoring system for living environment based on the single-chip. The temperature and humidity can be measured by DHT11 sensor. Mq-2 sensor is used to detect the leakage of CO, CO2, Formaldehyde, fire smoke and other harmful gases. The analog quantity is converted into digital quantity and the data is analyzed and displayed by AT89 C51. When the detected signal exceeds the safety threshold,the alarm is prompted.
