Street lighting is a vital component for urban safety and functionality, requiring regular maintenance to ensure optimal performance. This research explores the use of the long range (LoRa) technology in a mesh network topology for efficient streetlight monitoring and fault detection. By leveraging LoRa’s low-power, long-range communication capabilities, the system allows data transmission between streetlights over distances of up to 240 m. The mesh topology enhances the network’s reliability by enabling nodes to receive and retransmit data, ensuring robust communication even at extended distances. This approach facilitates real-time monitoring of streetlight conditions, enabling the remote detection of faults and the prioritization of maintenance tasks. The proposed system significantly reduces the time and resources needed for maintenance, providing an efficient solution for managing large urban streetlight infrastructures. The findings confirm the effectiveness of LoRa technology and mesh networking in enhancing streetlight monitoring systems, streamlining maintenance workflows, and improving overall service efficiency.
