Real-Time Fault Notification for Billboard Lighting System

This paper presents a technique to implement the alert system for the faults of billboard lighting system. The proposed system consists of the current sensor module SCT-013-005 used to measure the overall current consumption of the billboard lighting system, ARDUINO UNO R3 used as the controller to determine the faults, and GSM module used to remotely transmit faulty data to the data server as well as to the user mobile via short message service. The alert data composes the current consumption of lighting system, number of the bulbs with abnormal condition, and identification number of base station. In addition, the conditions for sending notifications can be set. The billboard lighting system using seven bulbs connected in parallel is employed to test the performance of the proposed notification system. Test results verify that the proposed system can function correctly.
