基于ZigBee和WIFI的甲醛检测系统设计

Design of formaldehyde monitoring system based on ZigBee and WIFI

使用传统的甲醛检测仪,不能同时对多个监测点同时进行检测,存在时间长、效率低等问题。本文设计了一种有效的多节点室内甲醛浓度快速检测方案。通过多个无线传感器节点同时在不同位置检测甲醛浓度数据,并将数据经ZigBee网络发送给协调器,并通过WIFI模块将甲醛浓度数据发送到智能手机进行显示,从而实现对多个空间甲醛浓度的实时、有效检测。

The traditional formaldehyde detector can not simultaneously detect multiple monitoring points,which has the problems of long time and low efficiency.This paper designs an effective multinode indoor formaldehyde concentration fast detection scheme.The formaldehyde concentration data are detected at different locations by multiple wireless sensor nodes at the same time,and sent to the coordinator through ZigBee network.The formaldehyde concentration data is sent to the smart phone through WIFI module for display,thus realizing real- time and effective detection of formaldehyde concentration in multiple spaces.
