摘要: The purpose of this study is to build an indoor air quality monitoring system based on wireless sensor networks (WSNs) technology. main functions the include (1) remote parameter adjustment and firmware update mechanism for sensors enhance flexibility convenience system, (2) nodes are designed by referring IEEE 1451.4 standard. This way, can automatically adjust be plug play, (3) calibration method strength measurement value's sensitivity accuracy. experimental results show that transmission speed improves 30% than Trickle, volume reduced 42% original volume, updating task in 5*5 network topology executed 1.79 times power consumption 30%. When baseline drifts, we use reference value. way reduce error percentage from 15% 7%.
