In the initial topic in basic physics in school and college, the concept of analysing a measurement error needs to be understood by students. This paper proposes the use of various sensors on smartphones for statistical error analysis which usually uses the classical method with repeated measurements. The smartphone sensors used were light, acceleration, and magnetometer sensors. The data from the sensor recording fluctuations for 10 s were analysed for the simple statistical figures and error. The experiment used three different conditions, namely placing the smartphone on a stable table, holding it with your hand, and bringing it closer to a notebook that played a 650 Hz tones. The experimental findings, the experimental conditions (environmental and blunder), and the specifications of the instrument affect the error. Students also can tell that the sensor takes repeated measurements so that it shows fluctuation data. This research contributes to offering the use of the latest technology, namely smartphones, for statistical error analysis for physics students.

在智能手机上使用各种传感器测量物理量的误差分析

在学校和大学基础物理的初始主题中,学生需要理解分析测量误差的概念。本文提出在智能手机上使用各种传感器进行统计误差分析,该分析通常使用具有重复测量的经典方法。使用的智能手机传感器是光、加速度和磁力计传感器。对来自传感器记录 10 秒波动的数据进行了简单的统计数字和误差分析。实验使用了三种不同的条件,即将智能手机放在稳定的桌子上,用手握住它,并将其靠近播放 650 Hz 音调的笔记本电脑。实验结果、实验条件(环境和失误)以及仪器的规格都会影响误差。学生还可以看出传感器进行了重复测量,以便显示波动数据。这项研究有助于使用最新技术,即智能手机,为物理学生进行统计误差分析。
