Description: An urban sensor is a device designed to monitor urban environments and infrastructure, collecting real-time data on various environmental and infrastructure variables. These sensors are an integral part of the smart city concept, where technology is used to enhance the quality of life for citizens and optimize resource management. Urban sensors can measure parameters such as air quality, noise, temperature, humidity, traffic, and energy usage, among others. Equipped with IoT (Internet of Things) technology, these devices connect to networks to transmit data to analysis platforms, allowing authorities and citizens to make informed decisions. The implementation of urban sensors not only helps identify problems in real-time but also facilitates urban planning and sustainability, contributing to a healthier and more efficient environment. Their relevance lies in the ability to transform data into actionable insights, thereby improving city management and fostering citizen participation in decision-making.
