It’s commonly known Microwave and Infrared are main detecting technologies in lighting controls. Both have the advantage and
disadvantage for industrial applications.
The remedy is to create Dual Sense by combining both technologies to make use of the advantage and bypass the disadvantage.
* HF: Microwave only
* PIR: PIR mode only
* HF+PIR: both PIR and microwave mode, to decrease the detection capability and detection
area. Only when both detections are activated, the motion is considered valid. This is
to prevent the sensor from false trigger by heat source, air conditioner, ventilation fans,
water pipe and elevators etc...
* HF/PIR: either PIR or microwave mode, to increase the detection capability and detection area;
* sensitive to minor motion.
* sensitive to radial movement.
* can be reflected by objects hence covering big detection area
* resilient to heat source, smoke and and air conditioner.
* penetrates walls, picks up motions outside of the office area;
* back wave detection, false trigger by motions at the back.
* can be false triggered by ventilation fans, water pipe, elevators
etc. in industrial application.
* no penetration, confined detection area.
* sensitive to tangential movement.
* resilient to motion object which has no heat radiation.
* can be false triggered by air conditioner, smoke and
other heat sources.

Light will not switch on
when natural light is
sufficient, even there is
motion detected.
The light switches on
automatically with
presence when natural
light is insufficient.
The light turns on at full or dims to maintain the lux level. The light output
regulates accroding to the level of natural light available.
