Introducing the NightLite Sensor
The Occupancy Sensor that is a Night Light!
![Page 3: The NightLite Sensor. Introducing the NightLite Sensor The Occupancy Sensor that is a Night Light!](https://reader036.vdocuments.us/reader036/viewer/2022062417/5516ad85550346a25b8b5930/html5/thumbnails/3.jpg)
Many people leave light on all night
24/7 lighted push-button provides enough light for 2 am trip to bathroom without having to turn on bright overhead lights!
Perfect for Hotel Bathrooms
If occupant wants to turn on overhead lights, the night light is the On/Off switch.
Passive Infrared (PIR) detection turns lights off if no occupancy

NightLite Sensor (WSD-NL)
Technical Features Passive Infrared (PIR) occupancy detection
provides coverage up to 10 feet for small hand motions and 20 feet for walking motions
Draws 1/10 of a Watt at 120VAC (7-10 times less than other night light devices
Can control lights and/or exhaust fans (1/4 HP Motor load)
Patented either/or wiring for hot and load wires makes installation simple (neutral & ground also required)
No minimum load requirements

Device contains microcontroller “brain” that is push-button programmable
Default operation is Auto On/Auto Off
Manual On is user selectable
Optional Reduced Turn-On Sensitivity Mode (eliminates PIR reflection off glass
Switch can also be disabled
Off time delay is factory set to 60 minutes, but is selectable up to from 15 minutes to 2 hours (in 15 min. increments)

Answer: Uses Passive Infrared (PIR) detection to “See”
Sensor detects “Heat in Motion”
You look like a moving 60 Watt light bulb!
How does a PIR Sensor Work?

How does a PIR Sensor Work?
Each lens segment generates a pair of collector beams The distance behind the lens is called the “Focal Length” The Focal Length determines the size of the beams
Detector
Lens
Two wafer thin Pyro-Electric elements are encapsulated and positioned behind a Fresnel lens

How does a PIR Sensor Work?
AUTO
The PIR Detector then “Sees” Changes in Energy
Body Heat in “Motion” Turns On the Sensor!

When People Move they Enter and Exit the Beams
