The NightLite Sensor

Introducing the NightLite Sensor

The Occupancy Sensor that is a Night Light!

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)

NightLite Sensor (WSD-NL)

Programmable Features

Mounts to standard switch box

Fits next to GFI receptacles

Vandal resistant lens

Conformally coated circuit board provides corrosion protection from condensation caused by high humidity (steam) in bathrooms

UL/CUL listed

5 Year Warranty

Made in the USA

Physical Features

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

The PIR Detector then “Sees” Changes in Energy

Body Heat in “Motion” Turns On the Sensor!
