摘要

设计了基于无线传输的空气比热容比测量装置，通过温度传感器和压强传感器将瓶内数据实时传送到上位机或手机ＡＰＰ端，并可以生成Ｐ?ｔ、Ｔ?ｔ、Ｐ?Ｖ图以及计算实验结果。实践证明，改进的空气比热容比测量装置可以使学生更直观地观察到实验过程中等体，等温的变换过程，加深物理知识的理解，同时保存的数据后期可以进一步进行数据处理以及实验扩展。

Abstract:

The Device for measuring specific heat ratio of air is designed and fabricated based on wirelesstransmission.The experiment data is transmitted from the bottle to the upper computer software or mobile appby temperature and pressure sensors, and P-T, T-t, P-V diagrams can be generated. It is demonstratedexperimentally that the improved device can enable students to observe the transformation process of mediumvolume and isothermal,understand the physics of process clearly ,and the saved data can be processed furtherin next experiment.

Key words: wireless transmission temperature sensor pressure sensor
