1. Introduction

The TLS 500 measures the reflection from objects
compared with background reflection. Any change in
the values is detected as an object and the output
switches.

1.1. Functionality

After switching on the TLS 500, it calibrates a
background measurement and saves this as a
reference value. When an object enters the detection
area, the reflection value changes.
The bigger the difference in light reflection between
the object and the background, the easier it is to
detect said object. High sensitivity comes from a
clear contrast between a detectable object and the
background: For example curtain, cloth, rubber,
asphalt, wood, concrete, earth, terracotta, cardboard
in comparison to people.
Poor sensitivity comes from a reflecting background
like marble, metal, glass, bright objects on bright
background, dark objects on dark background and
no background (the sensor does not see the floor).
