X-bee Wireless Sensor Networks for Temperature Monitoring

Abstract—This paper presents an embedded wireless sensor network (WSN) prototype system for temperature monitoring in a building. This network will be used for management of air conditioning systems at SIIT. The ultimate goal is to help saving the energy cost and reducing energy consumption. The system provides a web user interface for any user to access the current and past temperature readings in different rooms. The network consists of a data gateway or coordinator which wirelessly polls each WSN temperature-monitoring node located in each classroom. Each WSN node consists of a microcontroller on Arduino board and an Xbee wireless communication module based on the IEEE 802.15.4/Zigbee standards. The coordinator also has an Ethernet interface and runs a simple data web server. Hence, the coordinator allows data collection over Xbee and data access from web browsers.
