Motion Sensors

247 products
One of the easiest ways to reduce energy consumption and lower operating costs is with durable infrared motion sensors from Grainger. They can automatically turn the lights on or off when someone enters or leaves a specified area. Also called a light sensor, this type of passive infrared sensor (PIR sensor) is typically installed on walls or ceiling fixtures. When the motion sensor detects the body heat of someone moving in the room, it initiates a pre-programmed action, like turning off the lights. Grainger carries hundreds of motion sensors in a wide range of colors, configurations and time delay features. Check them out today.

Occupancy Sensor

Occupancy Sensor
Occupancy Sensors automatically turn lights off when occupants leave a room, which may help to reduce unnecessary energy consumption and lower costs. They are available with passive infrared (PIR) or ultrasonic (US) technology to detect users via body heat and movement.

Motion Sensor

Motion Sensor
Motion Sensors are available with passive infrared (PIR) or ultrasonic (US) technology to automatically turn lights off when occupants leave a room. The sensors can help to prevent wasted energy in unoccupied spaces. Models with adaptive technology are capable of setting adjustments according to seasonal changes, modified airflow, and furniture layout or occupancy pattern changes.

Occupancy Sensor with Nightlight

Occupancy Sensor with Nightlight
Occupancy Sensors automatically turn lights off when occupants leave a room, which may help to reduce unnecessary energy consumption and lower costs. They are available with passive infrared (PIR) or ultrasonic (US) technology to detect users via body heat and movement. Models with Nightlights allow users to easily locate a wall switch to turn lights on in dark or low-light environments.

Motion Sensor with Nightlight

Motion Sensor with Nightlight
Motion Sensors with Nightlights allow users to easily locate a wall switch in dark or low-light environments. Sensors with passive infrared (PIR) technology are capable of detecting body heat and movement to help turn lights on and off, depending on whether a room is occupied or vacant.

Vacancy Sensor

Vacancy Sensor
Vacancy Sensors automatically turn lights off when occupants leave a room, which may help to reduce unnecessary energy consumption and lower costs. Passive infrared sensors detect body heat to determine when the space is occupied. Ultrasonic sensors utilize sound waves to detect motion.

Dimming Vacancy Sensor

Dimming Vacancy Sensor
Dimming Vacancy Sensors utilize passive infrared technology to automatically help control the lights in an area. The sensors detect heat from occupants moving within an area to determine when the space is occupied and to automatically turn lights on or off.

Vacancy Sensor with Nightlight

Vacancy Sensor with Nightlight
Vacancy Sensors automatically turn lights off when occupants leave a room, which may help to reduce unnecessary energy consumption and lower costs. Passive infrared sensors detect body heat to determine when the space is occupied. Ultrasonic sensors utilize sound waves to detect motion. Models with Nightlights allow users to easily locate a wall switch to turn lights on in dark or low-light environments.

Wireless Occupancy Sensor

Wireless Occupancy Sensor
Wireless Occupancy Sensors offer easy use and installation. They can be moved and relocated to turn lights off when individuals leave a room. They are capable of sensing fine motion to avoid turning off when movement is minimal.

Wireless Occupancy Sensor Retrofit Kit

Wireless Occupancy Sensor Retrofit Kit
Wireless Occupancy Sensor Retrofit Kits are designed for use with compatible lighting systems to help in reducing energy consumption. The user-adjustable timers automatically shut off lights when rooms are vacant.

Daylight Sensor

Daylight Sensor
Daylight Sensors automatically adjust light levels based upon the amount of daylight present, to help provide convenience and energy savings. When installed, sufficient daylight will automatically signal the sensors to selectively deactivate the lighting. DHTD dimming units automatically dim lighting to help maintain preset light level conditions.

Wireless Daylight Sensor

Wireless Daylight Sensor
Wireless Daylight Sensors can help to automatically control lights for comfort, convenience, and energy efficiency. Lutron models with XCT™ technology are capable of sensing fine motion such as typing on a keyboard or writing with a pen.
