Dual Technology PIR Motion Sensors

Learn More
Motion sensors typically work with either PIR — passive infrared — or ultrasonic technology. Enerlites' dual technology occupancy sensors combine the best of both worlds for enhanced performance and improved reliability.

Some Enerlites products feature both PIR and ultrasonic sensors, allowing you to fine-tune performance for any room, and reduce the potential of false positives. Add to that a wide range of customizable settings and modes, and it’s easy to see why these products are professional’s choice in occupancy/vacancy sensor light switches.

About Dual Technology Occupancy Sensors
To understand the benefits of dual technology occupancy switches, it’s useful to look at the two types of sensors they contain:

• PIR sensors: PIR sensors detect small amounts of radiant heat emitted by people and animals as they move through a space. PIR sensors require a direct line of sight with the occupant, which makes them best for clearly defined spaces.
• Ultrasonic sensors: Ultrasonic sensors produce an inaudible sound wave and measure the amount of time between when it’s sent and when it returns. If that back-and-forth is disrupted by a foreign body in the space, it triggers the alarm.
Ultrasonic technology is more sensitive and doesn’t require a direct line of sight. As a result, it’s better for smaller rooms and oddly shaped spaces.

Dual technology occupancy switches contain both technologies. Most models will allow you to switch between modes if necessary. In dual mode, however, the switch only activates when both sensors are triggered.

What Are the Benefits?
The most significant benefit to a dual tech motion sensor switch is that it greatly reduces the possibility of false positives. Both PIR and ultrasonic sensors on their own have their pros and cons. Combining the two gives you the benefits of both, with none of the drawbacks.

Occupancy switches provide convenient hands-free operation, making them a smart choice for the laundry room, kitchen, bathroom, or anywhere else in the home where people often pass through while carrying bulky items. They’re also good for security, since they can dissuade unwanted visitors from lingering on your property when you’re not around.

By improving overall sensor accuracy, dual occupancy switches help you save energy and reduce your utility bills, while still enjoying the hands-free convenience and security of an ultrasonic and PIR sensor-based system.

Residential and Commercial-Grade Occupancy Switches
We engineer our occupancy sensor switches for performance in both homes and businesses. Our products include advanced features such as adjustable time delays and walk-through modes that allow you to configure their operation to reflect how people use and move through your space.

Dual tech occupancy switches typically work with most CFL, incandescent, and LED lighting products. They require a neutral wire to install. For more information and detailed specs, please visit individual product listings using the links on this page.
