Multipoint Temperature Data Logger and Display on PC through Zigbee using PSoC

Abstract: The vast potential of wireless sensor networks (WSN) is an emerging area of research in recent years. WSN consists of spatially distributed autonomous sensors to monitor the physical or environmental conditions like temperature, sound, pressure and to cooperatively pass their data through the network to the main location. The advantage of wireless sensor network is that they can be used with ease in the environment where wired system cannot be used or if used, are to be treated with caution. The WSN is built of nodes, may vary from few to several thousands. Each sensor node has typically several parts- radio transceiver with internal or external antenna, a microcontroller for interfacing with the sensors, energy source or battery. Zigbee is one of the latest and upcoming technologies in the field of WSN. In this paper we present the multipoint temperature monitoring using embedded PSoC microcontroller and Zigbee technology through a wireless data logger and display the temperature on the PC’s screen.
