Increase in population and the corresponding increase of roads has increased the number of the street light, for the roads and people’s safety, which rises investment and energy. Lighting consumes an adequate amount of energy in both outdoor and indoor. However different approaches are being proposed for making systems energy efficient and upgraded with the latest technology. Internet of Things (IoT) has been growing over the last few years in multiple applications and due to a growing need for smart street light, an innovative opportunity arises. Proposed work is to develop a smart street light system. This research gives precise and the best control over energy efficient street lighting system. It gives practical implementation using Long Range (LoRa) and Arduino micro-controller using sensors to gather information. The communication part is realized with Low Power Wide Area Network (LP-WAN) LoRa technology that combine low power and long-range capabilities.
