(What is the purpose of IoT sensors in smart cities?

IoT sensors in smart cities are primarily used to monitor and collect real-time data that enables optimized city operations. AI+ Network documentation explains that IoT sensors gather information from traffic systems, environmental monitors, energy grids, public safety devices, and infrastructure assets.

This real-time data allows city systems to make intelligent decisions, such as adjusting traffic signals, detecting environmental hazards, optimizing energy consumption, and improving emergency response times. When combined with AI analytics, IoT data supports predictive maintenance and proactive urban management.

IoT sensors themselves do not perform encryption or traffic prioritization, nor do they replace physical infrastructure. AI+ Network frameworks emphasize IoT as a data collection layer that feeds intelligent systems responsible for automation and optimization in smart city environments.
