The microwave sensor utilizes
high frequency technology to
based on occupancy.
It sends out electromagnetic waves that bounce off nearby surfaces, and uses the Doppler principle to analyze changes in the return waves to detect motion in the area. When motion is detected, the microwave sensor turns on the load, unless the ambient light level is greater than the daylighting set-point, or turns off the load when no motion is detected for the preset time delay.
Used in our Stair Lighter, TSL Series fixture.
When connected to an FS-PP Power Pack, the
FS-505 Series sensors use high frequency (40 kHz)
ultrasonic technology to sense motion within a
space and automatically turn lights on even when
the sensor has no direct line of sight to occupants.
After the area is vacated and the time delay has
elapsed, the sensors automatically turn the lights
off. Ultrasonic detection operates by transmitting
sound waves throughout an area and measuring
the speed at which they return. Movement increases
the return frequency, which triggers occupancy.
The Bluetooth-enabled sensor features a microwave occupancy sensor and photocell in a single unit.
By creating a wireless mesh network configured
by a smartphone app, field modifications of low end dimming levels, daylight harvesting, and group settings can be achieved without removing the fixture’s lens.
