一种基于STC89C52的室内空气检测系统

The Indoor air Detection System Based on STC89C52 Single Chip Microcomputer

为实现对室内空气质量的实时监测,保护人们的身体健康,设计一种基于单片机的室内空气检测系统。该系统以单片机STC89C52为核心,利用PM2.5粉尘、温湿度传感器检测室内粉尘的浓度及温湿度值,当浓度及温湿度值超过预先设定的阈值时,发出声光警报。该系统具有低功耗、高精度和灵活性强等特点,是一种实用的室内空气质量检测系统。

In order to monitor indoor air quality and protect people's health,an indoor air detection system based on SCM(single chip microcomputer)is designed.The system takes STC89C52as the core.using smoke.Using dust sensor to detect dust concentration.Using temperature and humidity sensor to detect temperature and humidity.When the concentration,temperature and humidity value exceeds the limit value,the sound and light alarm began to work.The system has the advantages of low power consumption,high precision and flexibility,and is a practical indoor air quality detection system.
