The LightHAWK2™ passive infrared wall switch Sensor uses passive infrared (PIR) technology to detect motion. The most affordable of the motion detecting technologies, this sensor type is ideal for detecting large motion in areas with an unobstructed view of the sensor. This sensor has a coverage area of up to 1000 sq-ft and 180 deg of detection. LHIR sensors feature Hubbell® controls patented IntelliDAPT® technology, which makes all the sensor adjustment decisions automatically. Throughout the products lifespan, smart software analyzes the controlled area and makes digital adjustments to sensitivity and timer settings. Occupancy sensors with IntelliDAPT® technology provide a maintenance free install and forget operation. With selectable operating modes - automatic ON/OFF or manual ON/automatic OFF - and a built-in photo sensor for automatic daylight harvesting, LHIR sensors are the best choice in todays market place.
