Automatic doors are entrance systems that open and close automatically, allowing people to enter and exit buildings without needing to push or pull the door. They are commonly found in places like shopping malls, airports, and hospitals, where high foot traffic makes manual doors less practical. These doors typically use sensors to detect when someone is approaching, triggering the door to open. There are different types of automatic doors, including sliding, swinging, and revolving doors. Sliding doors are often used in commercial settings, while revolving doors help maintain climate control in buildings. Automatic doors enhance accessibility and convenience for everyone, including those with disabilities.
