Proximity Sensor/Camera
Proximity Sensor
Introduction
The proximity sensor is predominantly applied in self-service terminals
such as e. g. kiosk terminals or ticket automats. Persons and objects of
comparable size who approach the kiosk terminal are detected by the
sensor and are signalled to the application program via evaluation
electronics.
The application can react to this message e. g. by sending out acoustic
signals or by changing the content on the monitor, as soon as a
customer approaches the automat.
Function
On radar sensor basis persons as well as objects of comparable size,
who move within the detection area of the sensor, are detected. The
signal of the sensor is extended by means of auxiliary electronics; i. e.
the signal backspaces 15 seconds after the last detected movement.
In case of detection of a further movement within this time frame the
delay time will be restarted.
