A smart city is like a giant robot that learns from people. It uses sensors and computers to know what’s going on, like traffic lights changing automatically when there are too many cars, or streetlights turning on only when it gets dark. It helps make life easier for everyone in the city.
Examples
- A streetlight turns on only when it gets dark outside.
- A bus arrives right when you need it because the city knows where you are.
- Your fridge sends a message to your phone saying it needs restocking.
