Design and Implement a Cost Effective and Ubiquitous Air Quality Monitoring System Based on ZigBee Wireless Sensor Network

A cost effective and user-friendly indoor air quality (IAQ) monitoring system based on ZigBee wireless sensor network implemented with the TI CC2430 ZigBee chip is described. In this proposed system, a temperature and relative humidity sensing module and a carbon dioxide sensing module were integrated in each ensor node which was placed in different indoor environment to monitor the IAQ parameters or indoor environment ubiquitously.
