How Do Automatic Door Sensors Work: Understanding the Technology

Discover how automatic door sensors use infrared and motion detection to enhance convenience and accessibility.

48 views

Automatic door sensors typically work with infrared or motion-detection technology. When the sensor detects a person or an object through body heat or movement, it sends a signal to the door's control mechanism. This triggers the door's motor to open. When the sensor no longer detects movement, it signals the door to close after a brief delay. These sensors enhance convenience and accessibility in many public and commercial spaces.
