简要分析利用M2M技术监测PM2.5

Brief Analysis of Use M2M Technology to Monitor PM2.5

本文以ATMEGA128单片机芯片为核心,实现了一个实用、经济的PM2.5无线监测系统网络。此系统把传感器技术与单片机的控制技术、AD转换技术相结合,实现对空气颗粒浓度的采集。把模拟量转换成数字量,经过单片机的处理计算后,显示PM2.5值。

This paper is based on the ATMEGA128 chip as the practical,economy PM2.5 wireless monitoring system of network.This paper mainly uses the single chip microcomputer to air concentration PM2.5 measurement system. This system combines the sensor technology with the single chip microcomputer control technology,and the AD conversion technology,realize the concentration of air particles in the collection, analog to digital quantity conversion,through calculation of the single chip displayed value PM2.5 on screen.
