Design of temperature recorder based on Bluetooth 5.0

传统的温度记录方式由于其高功耗,低效率以及环境因素影响的不确定性等导致实验人员的数据记录繁琐低效。本文提出了一种基于蓝牙5.0的温度记录仪的设计方案,采用了超低功耗蓝牙SoC,通过实际的温度测量实验采集了2 000个数据,对其进行了性能评估和参数测量,其工作时功耗仅为9.25 mW,同时其精度达到0.25℃。实验结果表明,该蓝牙温度记录仪较传统的电子温度记录仪具有更低的功耗以及更高效的记录方式,同时为实验人员提供友好的操作界面,有效的缩短了实验人员的数据记录时间。

Because of its high power consumption,low efficiency and uncertainty of environmental factors,the traditional temperature recording method makes the data recording of experimenters tedious and inefficient.In this paper,a design scheme of temperature recorder based on Bluetooth 5.0 is proposed,which adopts the Bluetooth SoC with ultra⁃low power consumption.2000 data are collected through the actual temperature measurement experiment,and the performance evaluation and parameter measurement are carried out.The power consumption is only 9.25 mW when it works,and the precision reaches 0.25℃.The experimental results show that the Bluetooth temperature recorder has lower power consumption and more efficient recording way than the traditional electronic temperature recorder,and provides a friendly operating interface for the experimenters,which effectively shortens the data recording time of the experimenters.
