Founded in 1987, Sensor Switch is the industry leader in developing
Occupancy Sensor Products & Technology for Lighting Control. Since
that time, we have built a long list of satisfied users across diverse
applications. Schools, warehouses, factories, offices, government
buildings, retail stores... you name it, we've sensored it! Our years of
experience and wide breadth of sensor and photocell products ensure
we can provide a reliable solution for any application or building type.
And while the industry struggles to catch up, Sensor Switch keeps moving
further ahead by introducing new products and technologies.
Product Highlights
Sensor Switch's products have many features that make them the most
technologically advanced in the industry:
- Continuous coverage patterns for Small Motion Detection
- Our Passive Dual Technology (PIR / Microphonics™) can literally "See & Hear" into areas with obstructions
- Relay Circuit Protection tested for over 400,000 switching cycles
- Widest array of sensors offered from any manufacturer
- Engineered and manufactured in the USA
Technical Services
To assist customers in the confusing world of lighting controls, Sensor
Switch provides advanced technical services such as:
- Modeling of facility lighting and occupancy patterns using our Data Logger Monitoring System
- Project layout and design using AutoCAD Software with custom Sensor Switch menus and symbols
- Hands-On Training at our on-site center
Sensor Switch is an Engineering Driven Company with several patents to its credit. Our sensors are constantly being improved; recent enhances to our product line include:
- Integration of a microcontroller into our sensors, enabling push button control and other advanced features
- Automatic photocell calibration and dimming control
- Interchangeable line and load wires on sensors making installation simple
Passive Infrared
Our sensors utilize a Passive Infrared (PIR) dual element detector
located behind a multi-segmented Fresnel lens. Each lens segment
generates a pair of collector beams. As heat given off by the human
body moves in and out of the beams, the detector "sees" this and
triggers the occupancy mode. Our lens designs create a continuous
array of beams that provide an even coverage so that the occupant
can not sit in a "Gap" undetected. Additionally, we fine-tune our
sensors to detect small motions even at great distances, while still
preventing "false trips".
Microphonics™ technology incorporates a microphone with the
PIR detector, providing an ideal solution for areas with
obstructions like bathrooms with stalls or open office cubicle
areas. This Passive Dual Technology (PDT) first detects motion
using the PIR and then engages the microphone to listen for
continued occupancy. Sophisticated circuitry tunes the sound
detection to sudden noise changes only and filters out the background
"white" noise. Patented by Sensor Switch, Microphonics™
provides a completely passive alternative to active ultrasound
methods of detection.
