Research and application of multi-node wireless skin temperature measurement system

Abstract

Skin temperature measurement has always been an important method for evaluating the warm-keeping clothing in winter. In order to realize synchronous real-time and accurate measurement of skin temperature, multi-person and multi-node wireless skin temperature measurement system is designed. Based on LoRa wireless transmission network, this research designed communication protocol and low power consumption circuit and developed a multi-person and multi-node wireless skin temperature measurement system. Twenty-four subjects were selected by this system in alpine regions for field tests on two kinds of warm-keeping clothing. The test results show that the skin temperature measurement system has the characteristics of long transmission distance, high measurement accuracy and simple operation and can meet the requirements of warm-keeping clothing test under extreme conditions.
