论文摘要
在本文中，使用皮托管的概念提出了一个用智能手机晴雨表测量空气速度的实验。在实验中，使用了APP Phyphox，该应用具有用于执行基于智能手机的实验的有用功能9,10。在提出的实验中，使用了App Phyphox中包含的两个数据分析工具和实验设置中的远程访问功能。该实验也是设计Phyphox中自定义实验的示例，任何用户都可以通过基于Web的编辑器9实现该实验。此外，还显示了如何使用外部蓝牙压力传感器来扩展实验，该实验可用于测量车辆的速度。 Phyphox版本1.1.0可以将外部蓝牙低能传感器集成到智能手机实验中。
In this article, an experiment to measure air velocity with the barometer of a smartphone is presented utilizing the concept of a Pitot tube. For the experiment, the app phyphox is used which has a set of useful features for performing smartphone-based experiments 9,10 . Both the data analysis tools included in the app phyphox and the remote access function to smartphones in experimental setups are used in the presented experiment. This experiment is also an example for designing customized experiments within phyphox which can be realized by any user via a web-based editor 9 . In addition, it is shown how an external Bluetooth pressure sensor can be used to extend an experiment, which is used here to measure the speed of a vehicle. Such an integration of external Bluetooth Low Energy sensors into smartphone experiments became available with phyphox version 1.1.0.
