Control the brightness of lights from your smartphone. Using a Bluetooth-connected app on your phone or tablet, you can schedule when lights turn on, adjust their brightness levels, and set their movement sensitivity. Also known as occupancy sensors, these dimmers turn lights on when motion is detected and off when people are away. You can override the motion sensor function with a tap on the app to manually switch or dim lights. They fit in standard wall plates.

Dimmers with infrared sensors detect changes in heat sources and require a direct view of people occupying the space to activate.

Dimmers with infrared/ultrasonic sensors minimize false activation by detecting changes in heat sources and motion. They can be set so that only one or both detection methods are required to activate and hold lights on.

For light controls with DC input voltage, you'll need a power controller to switch a 120V or 277V AC lighting circuit. Power controllers have a relay that switches a maximum 20-amp load.

Also known as occupancy sensors, these controls turn lights on when movement is detected and off when an area is unoccupied. All have a time delay to turn lights off after a set time.

Infrared sensors detect moving heat sources and require a direct view of the occupants.

Infrared/ultrasonic sensors minimize false activation by detecting changes in heat sources and motion. They can be set so that only one or both detection methods are required to activate and hold lights on.

Ultrasonic sensors detect movement and don’t require a direct view of the occupants.

Fine-tune motion-sensing light controls from your smartphone or tablet. Mounting on the ceiling gives these light controls a clearer view of the room than wall-mount sensors, so they detect motion over a larger area. They connect to a free downloadable app using Bluetooth. Use the app to adjust the amount of time lights stay on after people leave, set schedules, or override the sensor so lights are always on. Also known as occupancy sensors, they turn lights on when they sense movement and off after people leave.

Controls with infrared sensors detect changes in heat sources and need a direct view of people.

Controls with infrared/ultrasonic sensors have two detection methods to minimize false activation: infrared to sense heat sources and ultrasonic to sense motion. Use the app to adjust whether both or just one of these triggers will switch the lights.

Controls with a dimmer let you adjust the brightness of your lights.

Add companion switches to control lights manually without having to wire them directly into the light circuit. Attach them to any interior wall or outlet box and pair them wirelessly on the app.

Detect motion near your light fixture to turn lights on and off. Compared to switch-mount motion controls that detect from a single wall, these controls have a better view of the entire space since they sense motion from above. Also known as occupancy sensors, these controls have an infrared sensor that activates when it detects a change in heat. To work properly, they need an unobstructed view of your space. All have a time delay to turn lights off after a set time. Rated IP65, these controls are protected from washdowns.

These light controls monitor motion in a full circle for coverage in all directions. Those that cover 7,690 sq. ft. have lenses that can be swapped out to limit where they sense. Half-circle sensing lenses are best for concentrating coverage to a certain part of a room, such as a workstation or an entrance. Narrow sensing lenses are best for the end of aisles in spaces with high ceilings like those in warehouses and factories.

Monitor passersby and trespassers with light and an alert. For facility security, these light controls notify you on a smartphone app when they sense motion and turn on. You can also use the app to link additional lights and configure which lights turn on when movement is detected. Also known as occupancy sensors, they use an infrared sensor to detect changes in heat sources, so they need a direct view of people. The included mounting bracket swivels 90°, so you can install them on your wall or ceiling.

Power controllers (sold separately) are required to switch a 120- or 277-volt AC lighting circuit. They have a relay that switches a maximum 20 amp load.

Protect sensors from damage and prevent tampering—these guards won’t trip or block the sensors.

Never worry about turning lights on and off again. These controls turn lights on when people enter the room and off when rooms are empty or are bright enough. They use both an infrared motion sensor to detect the presence of people and a light sensor to determine ambient light. They have a swivel bracket to aim the sensor where people will be.

Power controllers (sold separately) are required to switch a 120- or 277-volt AC lighting circuit. They have a relay that switches a maximum 20 amp load.

Rated NEMA 4X and IP66 for use in washdown environments, these controls have an actuator that’s sealed to keep water out. An infrared sensor uses body heat to sense movement. They turn lights on when they detect motion and off when a room is empty or there’s enough daylight. To work properly, they need an unobstructed view of your space.

Detect chemical level with infrared light to avoid false switch activation caused by vibration in your tank. Also known as optical switches, these sense the level by reflecting light into a receiver that sends an output current to activate an alarm or control circuit. They are sensitive to light and should be shielded or used in enclosed tanks. Mount them horizontally or vertically.

SPST-NO switches activate when the tip is submerged in liquid and light stops reflecting into the receiver.

SPST-NC switches activate when the tip is exposed to air and light reflects into the receiver.

By detecting body heat, these modules sense when people are moving. Connect them to your development board to integrate them into alarm systems, automated lighting, and other applications.

Modules with an adjustable infrared motion sensor let you expand or lower the sensing distance. To connect them to a device, solder wires or headers to them.

Modules with a fixed infrared motion and thermal sensor can detect if a person is moving or even just present within the sensing distance. That means you could use them to automate lighting in an office where workers are sitting still. To connect them to your device, solder on wires or headers. For a solderless connection, use a Qwiic cord.
