Abstract: A microbolometer for measuring thermal radiation comprises an electrical circuit on a perforated plastic substrate. The electrical circuit comprises at least one thermistor having a temperature dependent electric resistance, wherein the thermistor is arranged to receive the thermal radiation for changing its temperature depending on a flux of the received thermal radiation. The electrical circuit is configured to measure the electric resistance of the thermistor for calculating the thermal radiation. The microbolometer is configured to cause a gas flow through the perforations for improving thermal characteristics.

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.
