摘要
本文对室内环境检测系统的各个部分做了相关介绍,对系统的实现方案和设计步骤进行论述。采用AVR系列的ATmega16单片机作为主控制器,温度的测量使用数字温度传感器DS18B20,湿度的测量使用电容式湿度传感器HS101,光照强度的测量使用光敏电阻,甲醛含量的测量使用MQ138,CO的检测使用MQ-7,氨气、硫化物、本系等气体的检测则使用气体传感器MQ135。室内环境检测系统不仅能够提供温湿度的相应信息,更重要的是能够检测到室内的有害气体,给人们提供一个安全的生活环境。
This article introduces each part in indoor enviroment detection system, expounds its implementation scheme and design steps. It adopts AVR series Atmega16 microcontroller as main controller, uses digital temperature sensor DS18B20 to measure temperature, uses capative humidity sensor HS101 to measure humidity, uses photosensitive resistance to measure light intensity, uses MQ138 to measure formaladehyde content, uses MQ-7 to detect CO, uses gas sensor MQ135 to detect ammonia, sulphides and other gases. Indoor enviroment detection system not only provides temperature and humidity information, more importantly, it can detect harmful gas in the room, so that it gives people a secure living enviroment.
