How does the automatic sensor door work?

The automatic door itself is equipped with a sensor probe that can emit an infrared signal or microwave signal. When this signal is reflected by a nearby object, it will automatically open and close.

Sensor doors refer to sliding sensor doors and flat opening sensor doors. "Induction" refers to an opening mode in automatic doors. Sensor door is the structure of sensor door in recent years. A kind of glass door widely used in shops, hotels, enterprises and institutions and other places. Its most direct feature is that it will automatically open the door when someone or an object approaches. When an object approaches, the door does not open. Sensor doors can be roughly divided into translation, rotation and push-pull types. Among them, the translation type and the rotation type are most suitable for setting up sensors.

1. Plane geometric shape. It consists of more than four planes, and the intersection lines of each plane are related to each other to form a space.

2. Geometric surface body. It is composed of geometric surfaces. It consists of the movement of the plane of the linear edge of the geometric surface around a straight line, and its trajectory forms a curved body.
