The purpose of Presence or Movement Detection is to ascertain when an area is either occupied or becomes unoccupied to control the environment. Different areas and applications require different techniques.

The lifetime of an individual component is mainly dependent upon the quality of the materials used. This of course has an impact on the manufacturing cost of the device.

You do not need to download and App. Simply use the inbuilt camera and point it directly towards the tube when the light is on.

Firstly lets address (no pun intended!) the initial commissioning. It is not practical to pre-commission a light so all commissioning is done after installation.

But the really clever part is found in the microprocessor control electronics. The result is nothing short of amazing: radiantly bright light all around the building at minimum energy consumption........

Intrinsically these High Bay Sensors are similar in attributes to a corridor sensor except for the flexibility of mounting them at a ceiling height exceeding 25 feet.....

They typically operate by generating a high-frequency pulse of sound, and then receiving and evaluating the properties of the echo pulse.....

Ultrasonic sensors “are based on the measurement of the properties of acoustic waves with frequencies above the human audible range,” often at roughly 40 kHz...

Steinel offers lights with integrated sensor swhich are called the RS pro series. These too can be networked in a master and slave configuration....
