Design and Implementation of a Radio Frequency Identification Automating Lighting and Electrical Appliance Control in An Office System

Radio Frequency Identification (RFID) technology offers an innovative approach to automating lighting and appliance control systems in office environments. This abstract outlines the design and implementation of an RFID control system that manages lighting and appliances in an office setting. Authorized RFID cards are used to activate appliances upon entry, while continuous RFID scanning ensures that devices are turned OFF automatically when no card is detected. The system was designed using an Arduino Nano microcontroller, an MFRC522 RFID reader, and a 5V relay module. Simulations were conducted using Fritzing, Tinkercad and Arduino IDE to validate practical circuit design and control logic. The physical prototype was tested in an office environment, demonstrating effective control of lighting and a connected 746W A/C appliance. The system was implemented in an office with ten 18W LED lamps achieving a lux level of 500 and 1 HP air conditioner. The ratio of controlled light with RFID to unmonitored RFID is 1:3 indicating that the RFID controlled light energy consumption is 67% lower. The results highlight the potential of RFID technology in modernizing office spaces, improving resource management, and minimizing energy wastage.
