基于Atmega16L的多功能室内环境监测仪

Design of Multifunctional Indoor Environment Monitor Based on Atmega16L

为了让业主及时了解室内空气状况,并且在出现安全问题情况下及时提醒业主采取相应的安全措施,以At-m ega16L单片机为核心,结合气体传感器阵列,开发了多功能、低功耗、智能化的室内环境监测仪器,实现对室内环境的温度、湿度、CO、CO2、碳氢化合物、甲醛的监测和显示,当CO、CO2、碳氢化合物、甲醛浓度超过限定值启动声光报警。文中主要介绍了多功能气体监测仪的硬件设计和软件设计。

In order to acquire the indoor air environment,this paper presented a way to design an indoor environment monitor based on Atmega 16L and gas sensor array.It can measure the indoor temperature and humidity and the concentration of CO,CO2,HC and HCHO,which can be displayed on LCD.It will give alarm if the concentration of CO,CO2,HC and HCHO has reached limit value.The paper elaborates the software and hardware design of the indoor environment monitor.
