Microwave and Infrared Sensor System, also known as a 2-in-1 Combined Sensor

A combined sensor integrates both microwave and infrared technologies to detect motion within a designated range and automatically trigger the opening and closing of doors. This type of sensor is particularly suitable for frameless glass doors or automatic doors where installing a visible sensor (such as a peephole) is not desired.

Microwave Signal Operation
Microwave signals detect motion from people, animals, or objects within the sensor’s range. When movement is detected, the microwave sensor activates the automatic door to open. The door will close once no further motion is detected. The detection range of the microwave sensor can be adjusted, but the closing delay time cannot be configured.

Infrared Signal Operation
Infrared signals project a curtain of light directly in front of the door to detect motion from users entering the area. A key feature of infrared sensors is their built-in safety system: if a person stands still within the detection zone, the door remains open. The duration for which the door stays open depends on the configured time setting, with the standard being 60 seconds or 1 minute.
