A pair of automatic doors. An automatic door, also known as an auto door, is a door that opens automatically, without the need for human intervention or usually upon sensing the approach of a person. A person can be detected by microwave pulses, infrared sensors, or pressure-sensing pads. [1]
Triangulation sensors which are mounted on the door and move with the door to provide safety. Reflective and camera technologies do not perform well on moving swing doors, because they typically depend upon detection of changes in the background. A sensor mounted on a swing door system is constantly in motion, so the background (i.e. floor ...
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
Conceptual through-beam system to detect unauthorized access to a secure door. If the beam is interrupted, the detector triggers an alarm. A photoelectric sensor is a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver.
An example of the inductance loop installed in the road for cars and bikes Schematic of such a detector See also: Traffic count Vehicle detection loops, called inductive-loop traffic detectors , can detect vehicles passing or arriving at a certain point, for instance approaching a traffic light or in motorway traffic.

The electromagnetic parking sensor (EPS) was re-invented and patented in 1992 by Mauro Del Signore. [2] Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided. Once an obstacle is detected, the sensor continues to signal the presence of the obstacle even if the vehicle momentarily stops.
