The technology employed in smart cities for data collection primarily involves Internet of Things (IoT) devices. These interconnected sensors and systems monitor various urban parameters, including traffic flow, air quality, waste management, and energy consumption. The data collected is analyzed to improve services, enhance sustainability, and optimize operational efficiency within the urban environment. By leveraging real-time data, smart city technologies facilitate informed decision-making, enhance public safety, and improve residents' quality of life. This interconnected infrastructure is crucial for creating resilient and adaptive urban settings.
