  • 1. SMART WIRELESS TEMPERATURE DATA LOGGERUSING ZIGBEE 802.15.4ABSTRACT:This paper proposed a portable wireless data acquisition system for temperaturein real time process dynamics. Process variables (like temperature, pressure, flow, level)vary with time in certain applications and this variation should be recorded so that acontrol action can take place at a defined set point.This paper proposes an 8 bit embedded platform for a sensor having a networkinterface using the 802.15.4, ZigBee protocol, that is specially designed for the sensorsnetwork. The ZigBee protocol is a wireless technology developed as an open globalstandard to address the unique needs of low-cost, low-power, wireless sensors network.This wireless data logger senses and monitors the variations in the local temperaturethereby transmits the data within the range to an assigned embedded processor basedserver. Received temperature is displayed on a local liquid crystal display (LCD) onassigned server and simultaneously on a computer.www.nanocdac.com www.nsrcnano.com branches: hyderabad nagpur
