The temperature data acquisition module to measuring equipments temperature after power, temperature and contact through the wireless transmission will measure the bottom to the central processing module. The temperature data center module will receive the analysis, then the display module shows the collected temperature, and showed the temperature change curve in pc.. The PC software developed by VisualC++, realize the management and analysis of the system, provide parameter setting, alarm, display and other functions. Keywords MSP430 microcontroller, temperature sensor, wireless transmission module, PC 目錄 1 目 錄 摘 要 ................................................................................................................................
