Design and Implementation of Smart Highway Streetlights for Sustainable Urban Infrastructure

Abstract

In order to improve energy efficiency and safety, the project "Design and Implementation of Smart Highway Streetlights for Sustainable Urban Infrastructure" makes use of motion sensor Passive Infrared (PIR), monitoring system DHT22, MQ-4, and LDR sensors. In order to save energy, the PIR sensor only turns on the streetlights when it detects the presence of cars and pedestrians. While the MQ-4 sensor detects gas levels to guarantee air quality standards, the DHT22 sensor keeps an eye on the environment, providing information on temperature and humidity. By adjusting the streetlights' brightness in response to ambient light levels, the LDR sensor maximizes visibility while consuming less energy. These sensors can be integrated into a centralized monitoring system to enable remote management and real-time data collection, guaranteeing effective operation and maintenance. In addition to reducing energy consumption and operating expenses, this smart streetlight system makes cities safer and more environmentally friendly. The study's findings suggest that there is a great deal of room to improve environmental monitoring and lower energy use in urban infrastructure projects.
