Outdoor motion sensor lights are intelligent LED lights that can be automatically triggered to turn on by nearby movements. Outdoor lighting for residential spaces and commercial properties is a distinct application where energy efficiency, visual satisfaction, safety and security go hand in hand. Outdoor lights are used to illuminate a building’s exterior and the surrounding landscape to increase the usability of outdoor living spaces, to create visual expansion and continuity between the indoors and outdoors, and to bring a sense of safety and security to a dark yard. Creating an outdoor lighting solution requires designers to plan not only where the fixtures should be placed, but also when these lights should be activated. A good outdoor lighting solution puts the right amount of light where it is needed and when it is needed. Among the myriad of lighting control strategies, motion activated lighting provides the most cost-effective way to adapt lighting to real-time needs on an individual level.

Motion sensors for use in outdoor lights can be categorized into active or passive devices based on whether they produce an energy output and then sense the response of the environment to that energy. Most outdoor motion detectors use either a passive infrared (PIR) sensor or an active microwave sensor to detect motion. The two technologies may also be used in conjunction to achieve maximum reliability. Dual-technology (DT) sensors activate lights only when both sensors detect the motion. A PIR sensor detects motion by measuring changes in infrared radiation emitted from objects that generate heat. Microwave sensors are commonly Doppler radars that send out ultra-high frequency radio waves known as microwaves and detect motion by measuring changes (shifts) in frequency of waves bounced off by a moving object within the detection zone.
