Abstract
Measurement of indoor lighting intensity is generally still performed manually using portable lux meters, where measurement points are determined based on user estimation. This approach may lead to inconsistencies in measurement results, particularly in rooms with varying sizes and configurations. This study aims to design and develop a lux meter prototype based on automatic measurement point determination to improve the accuracy, efficiency, and consistency of lighting measurements. The proposed system integrates a light intensity sensor with a microcontroller and an automatic coordinate determination mechanism based on room dimensions and standard measurement point distribution methods. The prototype is capable of identifying measurement points, acquiring illumination data, and storing measurement results in real time. System performance was evaluated under various lighting conditions and room dimensions. The experimental results demonstrate that the proposed prototype can automatically determine measurement points with good positional accuracy and provide stable illumination readings compared to conventional manual methods. Furthermore, the system accelerates the measurement process and minimizes operator subjectivity and human error. The proposed prototype is expected to provide an alternative solution for building lighting audits, energy efficiency evaluations, and the implementation of automated lighting monitoring systems in smart buildings.
