Abstract

A sensor device includes a passive infrared sensor, a control circuit, and a lens that directs infrared radiation onto the passive infrared sensor. The lens includes an obstruction that asymmetrically blocks transmission of infrared radiation through the lens. The control circuit is configured to determine the direction of crossing of individuals passing in front of the sensor device based on sensor signals from the passive infrared sensor.
