Automatic Light Controller Using Arduino Uno Based on Ultrasonic Sensor Pengendali Lampu Otomatis Menggunakan Arduino Uno Berbasis Sensor Ultrasonik
Main Article Content
Abstract
This study designs an automatic lighting control system based on the Arduino Uno using an ultrasonic sensor and a relay to improve energy efficiency. The system operates by detecting the distance of an object, where the light turns on when an object is detected within a distance of ≤100 cm and turns off when the distance exceeds 100 cm. The testing results indicate that the ultrasonic sensor accurately measures distance and that the system functions according to the programmed instructions. Overall, the proposed system is effective in automating lighting control while reducing electrical energy consumption.
