A design for a multi-temperature data collection is presented based on wireless transmission technology. The wide range temperature detection and modularization design method based on MSP430 are emphatically discussed. Finally, the temperature is displayed in the personal computer, so as to realize temperature telemetry. The application results show that the detection accuracy of 0.5 ℃and the maximum detection distance of 100 m can be achieved. The proposed method is of good practicability.
