Sistem Pengendali On/Off Otomatis Saklar dan Konsumsi Daya Listrik Neon Box Berbasis Internet of Things (IoT)

Abstract

Energy efficiency refers to the effort to utilize energy in an optimal and purposeful manner. Inefficient energy usage is still commonly observed, particularly in the operation of neon boxes that remain illuminated during daylight hours due to human oversight. Additionally, the power factor of the load also significantly affects energy efficiency. This study applies the BH1750 light sensor to develop an automatic on/off switching system for neon boxes based on the measured light intensity. The system uses a TL-LED lamp as the load. The experimental results indicate that the BH1750 sensor functions accurately in accordance with the predefined setpoint: when the detected light intensity exceeds 100 lux, the lamp is automatically switched off; conversely, when the intensity falls below 100 lux, the lamp is switched on. The TL-LED lamp demonstrates high efficiency, with a power factor of approximately 0.9, which is close to the ideal value. Furthermore, the system proves effective in reducing operating time, as it decreases the neon box's active hours by 35 hours over a 10-day period, resulting in an energy saving of 2.52 kWh.
