基于ATmega128的多参数室内环境监测仪的设计与实现

为了有效克服目前国内的环境监测仪器可测参数单一、不能实时监测环境的变化、采集精度低以及无报警措施的缺点,研制了基于ATmega128单片机技术和传感器技术的室内环境监测仪.多参数室内环境自动监测仪能够对温湿度、CO、甲醛、CO2、SO2,以及可吸入颗粒等多参数进行动态测量、实时分析、自动分等级报警,并根据测量结果,采取相应的反馈动作.已对监测仪的各个模块进行软硬件调试,系统工作稳定,参数的测量误差均在允许范围之内,可投入使用.

Design and Implementation of Multi-Parameter Indoor Environment Monitor Based on ATmega128

In order to effectively overcome the shortcomings of the current domestic environmental monitoring instrument,such as single parameter measurement,poor real-time monitoring,low accuracy and non-alarming measurement,a multi-parameter indoor environment monitor based on ATmega128 microcontroller technology and sensor technology is developed.Multi-parameter indoor environment monitor can measure temperature and humidity,CO,formaldehyde,CO₂,SO₂,and inhalable particles and so on,and can provide dynamic real-time analysis and automatic level alarm.According to the measurement results,it will take corresponding feedback action.The experiment has been carried out about hardware and software of the system.The system possesses high measurement precision,good real-time,reliable performance and its metrics meet the national standard which can be put into use.
