Design of Wireless Temperature Sensor Network Based on CC2530

For the harsh industrial environments with high temperature,this paper describes a solution which is based on the CC2530 chip to measure the temperature and designs a wireless temperature sensor network with temperature sampling module which is consisted of K-type thermocouple and analog-digital conversion chip MAX6675. The system using CC2530 chip as the hardware core applies ZigBee wireless transmission technology to the distributed temperature measurement. This wireless temperature sensor system overcomes the limitations of wired sensor networks and achieves a high accuracy in temperature measurement. Experimental results show that the system can operate in real time,stable and accurate. The error remains within 2℃ in temperature,meeting the industrial demands.
