Which sensor is used for door opening?
Most automatic gates nowadays use optical sensors or motion detectors, which are installed on the sides of the gate to trigger its opening and closing. As the name suggests, these sensors detect motion in front of the door. An antenna is installed on the gate header pointing in the outward and downward direction.
Which sensor tell your system if something open or close?
Door contact sensors
Door contact sensors communicate to a security system if doors or windows are closed or open.
What is a door auto sensor?

Where is the sensor on a garage door?
The standard sensor works the same as on any other door. The two pieces are installed next to each other, one on the door and one on the wall right next to the door. When the garage door is raised, it breaks the circuit and sets off the alarm.
Where are the sensors on a garage door?
Garage door sensors utilize a photo-eye sensor and a beam of infrared light that goes between the two units. The units are placed near the ground on either side of the garage door. If the beam of light is interrupted while the garage door is closing the door will stop and rise back up.
