Abstract – Light is recognized as a fundamental form of energy that ought to be a primary focus in our daily experiences. There exists a profound connection between humans and light, and it is acknowledged that the integration of the Internet of Things (IoT) has the potential to amplify overall efficiency while significantly reducing costs. Through the incorporation of IoT technology, faults in street lights can be detected effortlessly, facilitated by the employment of two Light Dependent Resistors (LDR) sensors. This innovative approach allows one sensor to ascertain ambient light by monitoring prevailing weather conditions, thereby enabling automatic adjustments to the brightness of street lights. The implication of this technology is a substantial reduction in manual labor and a minimization of inconvenience to the general populace.

In instances where a street light malfunctions, it is designed to alert the relevant authorities using a Python Kivy application, thereby streamlining the resolution process for both the public and the authorities involved. This procedure is further refined through the use of an additional sensor dedicated to identifying malfunctions directly within the street lights. The inclusion of the WiFi module ESP232 plays a critical role in this system, as it is responsible for the transmission of pertinent data to the routers. Accessibility to this data is achieved through the Python Kivy application, which is instrumental in notifying the authorities regarding street light issues and pinpointing the exact location of the malfunction. Through this meticulously designed system, the efficiency of addressing street light malfunctions is significantly improved.

1. INTRODUCTION

   The current method of maintaining the lighting grid is characterized by staff being required to conduct regular patrols with faulty lamps, a process that can extend over days or even months to complete. Additionally, reliance is placed on the community to report any dysfunctional streetlights.

   The use of an automatic street lighting system that detects faults would eliminate wasted time and errors in the detection and reporting of malfunctions. Faults would be automatically detected by sensors within seconds of occurring, allowing technicians to be quickly directed to and repair the faulty light, significantly reducing the maintenance time required and saving up to 42% in maintenance costs.

   The implementation of an automatic street lighting maintenance system could also simplify the process for municipalities to expand the street lighting system into additional areas and enhance the availability of streetlights in underserved communities. Moreover, the rapid detection and repair of faulty lights are expected to greatly enhance safety conditions for both vehicles and pedestrians.

   In our daily lives, linemen are tasked with manually setting the fault work. This arrangement can be problematic for the people residing on the streets, as they must inform the linemen of any issues. Additionally, the lights remain on from 6 PM to 6 AM, resulting in substantial power loss. To tackle these challenges, a solution based on IoT technology is proposed. This project aims to conserve energy by utilizing LDR to adjust lighting according to weather conditions and to detect faults, thus minimizing the need for manual inspections.

   The cost efficiency of the implemented solution has been successfully demonstrated through an analysis of its performance relative to the associated expenses. An
