How the Internet of Things Is Creating Smart Cities and Smart Homes

IoT device count exceeds 18B globally. Smart cities use IoT for traffic management, waste collection, air quality monitoring, and energy optimization. Smart homes integrate lighting, security, HVAC, and appliances. But security concerns persist: many IoT devices have weak security, creating botnet risks. The Matter protocol aims to standardize smart home interoperability. The real value of IoT is in data: millions of sensors generating data that AI can analyze to optimize systems in real-time.
