Occupancy Sensors have come a long way in just the past few years.

From the simple “lights on / lights off” of motion detection of early systems, new complete systems from the likes of Lithonia Lighting (Acuity Brands) feature a set of new technologically advanced features and controls, all tied together wirelessly or wire-line through integrated control panels.

The Sensor Switch product line is Acuity’s newest entry in the occupancy sensor field, featuring what the company calls “Microphonics” — microphones placed inside the sensor to capture better sound for occupancy detection without transmitting sound waves into the area. Combined with passive infrared (PIR) motion-detection technology, Microphonics amp up both the scale and scope of occupancy sensing, offering tighter control, more sensitive trip settings and user control over signals and system response times.

“Miswire Protection” is another feature of the Sensor Switch line, offering reversible line and load connections that make products impossible to wire backwards, thus eliminating potential job-site delays due to mis-wiring.

Acuity offers patent-pending convertible neutral technology to enable the sensors to convert from a no-neutral to a neutral-and-ground connection in seconds.

Additionally, all photo controls feature self-calibration, with an automatic set-point calibration mode regardless of time of day or daylight conditions.

You can even program the Sensor Switch family via an easy-to-use App available for your smartphone. The Sensor Switch Mobile App uses a smartphone camera flash or Bluetooth settings technology to configure settings on VLP-enabled occupancy sensors, photocontrols and luminaire-embedded sensors. Users can set occupancy time delays, trim values, photo control options and more via their phone.

Sensor Switch products, through energy savings generated by switching lights down or off during periods of lower or non-occupancy, aid in ensuring buildings meet applicable energy codes such as Title 24, ASHRAE and IECC.
