Wireless Reprogrammable Real Time Remote Temperature Measurement System

Wireless re-programmable real time remote temperature measurement system is able to measure the real time temperature of various remote locations with an accuracy of 0.25°C each. The existing methods use wire transmission. Hence if fault occur means, cable replacement cost is high. The proposed system uses wireless transmission (Zigbee) with the data rate of 256Kbytes/s, to transmit the measured temperatures to the central control system for monitoring purpose. In addition, the proposed system incorporates feature that controls the temperature at the remote locations in real time. Because of using Zigbee, this system effectively works for a distance of more than 60m between the temperature measurement locations and the control station and also its performance when compared to Bluetooth is high. Since this proposed system uses a reprogrammable controller, it is possible to customize the design to various industrial applications.
