Smart wireless temperature data logger using IEEE 802.15.4/ZigBee protocol

Abstract

This paper proposed a portable wireless data acquisition system for temperature in 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 a control action can take place at a defined set point. This paper proposes an 8 bit embedded platform for a sensor having a network interface using the 802.15.4, ZigBee protocol, that is specially designed for the sensors network. The ZigBee protocol is a wireless technology developed as an open global standard 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 temperature thereby transmits the data within the range to an assigned embedded processor based server. Received temperature is displayed on a local liquid crystal display (LCD) on assigned server and simultaneously on a computer.
