Ultrasonic & Microwave – Active Presence Detection

Ultrasonic and microwave detectors operate

by constantly sending out signals to detect

activity in the area.

If these signals come back unchanged, there

is no movement.

When movement is detected, this causes

a distortion of the signals and the detector

switches the lights on.

Lights are kept on for as long as there is

movement in the area.

When movement ceases and the signals

show no distortion, the switch-off timer is

activated.

If no movement is detected within this period

(set to 20 minutes in this example), the lights

switch off.

Lights remain off until movement is again

detected in the monitored area.

Using all three

major types of

presence detection

technology;

passive infrared,

ultrasonic and

microwave as

demonstrated in

the above captions,

gives optimum

control covering

a vast array of

applications and

scenarios.

Microwave

and Ultrasonic

presence detection

technology

enables the range

and sensitivity

to be adjusted to

ensure a tailored

detection pattern

to suit any

application. Can

be used in offices

including open

plan areas.
