In this study, it is aimed to calibrate an LDR-Lux meter with a calibration setup which includes a light bulb whose brightness can be changed by using a dimmer circuit, a data acquisition card, a smartphone and a lux meter application. In order to make the measurements more accurate and to prevent errors in the measurements, a smartphone and a laptop were connected to each other via internet browser and the data obtained with physical phone experiments was displayed on the computer screen instantly. In the experimental setup, the brightness of the light was changed with the dimmer circuit and height adjustment. The data were obtained as a result of 32 experiments for different illumination values. As a result of this study, it is seen that the calibrated experimental setup works with high accuracy. With this experimental setup, it is thought that students can also easily test the inverse square law of light. The main factors that make this experimental setup effective are that, unlike other studies in the literature, a professional lux meter is not used and the cost of the developed LDR-Lux meter is very low.

在本研究中，其目的是通过校准设置来校准LDR-Lux测量仪，该校准设置包括一个灯泡，该灯泡的亮度可以通过使用调光器电路，数据采集卡，智能手机和照度计应用程序进行更改。为了使测量更加准确并防止测量错误，通过互联网浏览器将智能手机和便携式计算机相互连接，并将通过物理电话实验获得的数据立即显示在计算机屏幕上。在实验设置中，光线的亮度随调光器电路和高度调节而改变。数据是针对不同照明值进行32次实验的结果。作为这项研究的结果，可以看出，经过校准的实验装置具有很高的精度。通过此实验性设置，人们认为学生也可以轻松地测试光的平方反比定律。使该实验设置有效的主要因素是，与文献中的其他研究不同，该技术没有使用专业的照度计，而且开发的LDR-Lux计的成本非常低。
