Solutions for Infrared Motion Detectors

Littelfuse offers protect, control, and sensing solutions to ensure robust, reliable designs of infrared motion detectors that will result in fewer field failures and a more cost-effective and profitable product. Smart homes and buildings are benefitting from intelligent technologies that enable them to be safer, more convenient, and energy-efficient. Infrared motion detectors combine convenience, safety, and energy conservation. Infrared motion detectors sense occupancy in an area that can then activate lighting, the HVAC system, or the alarm.
