Automatic doors can be triggered in several ways, but usually by a active infra red sensor that detects traffic approaching. Sensors for automatic doors are generally:

• A pressure sensor – e.g., a floor mat which reacts to the pressure of someone standing on it.
• An infrared curtain or beam that shines invisible infra red light from sensors; if someone or something blocks the beam the door is triggered open.
• A motion sensor that uses low-power microwave radar for the same effect.
• A remote sensor (e.g. based on infrared or radio waves) can be triggered by a portable remote control, or is installed inside a vehicle. These are popular for garage doors.
• A switch that is operated manually, perhaps after security checks by a guard. This can be a push button switch or a swipe card.

Automatic doors are essential for climate control and useful for the safe passage and entrance for the disabled.
