An intelligent environment is a place where things are made really easy for people. It's like having lots of helpers who already know what you need and want, so you don't have to ask them for anything.
In an intelligent environment, sensors are placed all around to help know what's going on. These sensors can see what's happening, like when you walk into a room, or hear noises, like when someone knocks on the door. They can also feel things like heat or humidity in the air.
These sensors then talk to computers, which are like really smart brains that can make decisions quickly. In the intelligent environment, the computers use the information from the sensors to do things like turn on the lights when you walk into a room or start playing your favorite music when you enter a specific area.
The best part is that you don't have to do anything to make it happen! It's all done for you automatically.
Overall, an intelligent environment helps make your life simpler and easier by anticipating your needs and taking care of them for you.
