An FPGA based real-time remote temperature measurement system

Abstract

This paper presents a wireless re-programmable real time temperature measurement system designed using the hardware description language and realized in hardware using the field programmable array (FPGA). The proposed system is able to measure the real time temperature of various remote locations with each of them to an accuracy of 0.25 °C. It uses wireless transmission with the data rate of 115 Kbytes/s, to transmit the measured temperatures to the central control system for motioning purpose. In addition, the proposed system incorporates feature that controls the temperature at the remote locations in real time. This system effectively works for a distance of 60 m between the temperature measurement locations and the control station. Since this proposed system uses a re-programmable controller, it is possible to customize the design to various industry applications. This paper presents the simulation and experimental results of the proposed system.
