Human presence detection

Human presence detection means finding out if there is someone in a room or area. It's like playing a game of hide-and-seek, but instead of looking for people behind curtains or under beds, we use special tools and sensors that can detect if there is a person in a particular place.

For example, if you enter a room and turn on the light, you might notice that the lights turn on automatically without having to flip a switch. This is because there is a device called a motion sensor that detects your movement and sends a signal to the lights to turn on.

There are also other types of sensors that can detect human presence. One of them is a heat sensor that detects the warmth of a person's body. Another type is a camera that uses facial recognition to identify the presence of a person.

These devices are often used for security purposes, such as in homes, offices, and warehouses. They can also be used to conserve energy by automatically turning off lights or reducing the heating or cooling systems when no one is present.

In summary, human presence detection is like having a superpower that can detect if there is someone in a particular place without physically seeing or hearing them. It helps keep our homes and workplaces secure and saves energy by reducing waste when there are no people around.
