Occupancy Sensors, Passive Infrared, 2Circuit, 120V AC, White

Standard Passive Infrared Technology requires a clear, unobstructed line of sight for detection, because it senses occupancy as movement of heat emitted from the body against the background space. A segmented Fresnel lens divides a coverage area into zones. Movement across zones is interpreted as occupancy. Excellent for small room control.
