A smart environment is a place where technology helps people feel safer, more comfortable, and more connected. It can use sensors and other devices to detect changes in the environment, like temperature and sound levels, and then react to those changes. For example, a smart home might use sensors to recognize when somebody is home, and then adjust the lighting and temperature to make them more comfortable. Or a smart office might use sensors to detect if somebody is nearby and turn on the lights for them. Smart environments can also be used to help create safer places by tracking people, sending warnings if there is a security breach, and providing guidance to emergency personnel.
