For instance, IoT-powered smart traffic systems have drastically cut pollution and commuting times in places like Singapore. This transformation showcases how IoT is used in smart city projects to address longstanding urban issues.

Waste management has traditionally been a labor-intensive and inefficient process. The Internet of Things enhances this by enabling intelligent trash cans equipped with sensors that monitor their capacity. These sensors send data to local authorities, so they can make collection routes and schedules more efficient. The smart city IoT applications in waste management extend beyond rubbish pickup. For instance, IoT can help track recycling rates and identify areas where awareness campaigns are needed. By making waste management more transparent and efficient, IoT contributes to cleaner, greener cities.

Energy Efficiency and Smart Grids

Cities’ energy use contributes significantly to the world’s carbon emissions. This is addressed with IoT-enabled smart grids, which more effectively distribute electricity and track energy consumption in real time. The impact of these smart city devices goes beyond individual households. By reducing energy wastage at scale, cities can lower their overall carbon footprint, aligning with global climate goals. These advancements underline the critical role of the Internet of Things for smart cities in building sustainable urban environments.

IoT-Enabled Surveillance Systems

States are increasingly paying attention to the safety of the citizens, especially in large cities with a high population density. IoT-enabled surveillance systems use high-resolution cameras, motion sensors, and artificial intelligence algorithms to monitor and find dangers in real time. In comparison with conventional systems, IoT-powered surveillance examines enormous volumes of data and spots trends or odd activity that can point to a security breach. For instance, some cities use IoT to monitor crowded areas during events, alerting authorities to potential hazards like overcrowding or suspicious behaviour. These systems demonstrate how IoT is used in smart city initiatives to improve safety without compromising efficiency.

Emergency Response Enhancements

This function of smart city systems can be separated, although it is also relevant to public safety. Integration of advanced IoT systems allows detecting accidents or fires at strategic enterprises or multi-storey buildings. A striking example in this question is Japan. The state widely uses technology to prevent and mitigate the impact of natural disasters. One of the main tasks is the timely evacuation of the population. For example, one of the systems uses drones equipped with an infrared camera. Drones capture territory after a natural disaster, and transmit information in real time. Moreover, IoT devices can provide ambulances real-time traffic updates during a medical emergency, guaranteeing the quickest path to the destination. This highlights how IoT and smart city technologies work to save lives and protect communities.
