ZigBee Wireless Sensor Network for Indoor Air Quality Monitoring

Although the number of wireless standards with the development of new technologies is increasing, ZigBee protocol still finds its way to be dominant technology for low-cost and low- power applications that are used in wireless monitoring and control systems. Open source standard and the mesh networking provide high reliability and larger range. ZigBee has been designed to support thousands of networked devices. This paper presents design of wireless sensor network for monitoring air temperature and humidity in classrooms. ZigBee modules are configured to run in API mode using mesh topology. To achieve greater scalability coordinator node periodically scans entire network and updates monitoring data in case of disconnected or newly added nodes. Wireless sensor network is designed using Arduino platform and XBee modules based on IEEE 802.15.4/ZigBee standards.
