Abstract：In this paper, we proposed a wireless temperature monitoring system with high precision and low power consumption based on the high temperature gas absolute pressure traceability device. We used PT100 temperature sensors to collect temperature data and then used Lora technology to transfer data wirelessly and engineer a monitoring software using the graphical programming language LabVIEW, which realizes the functions of real-time temperature monitoring and recording. Extensive experimental results demonstrate the accuracy, low power consumption and convenience of our system.
