Infrared Ray SensorProvides ControlledTemperature in2007 Lexus

Sensors are making luxury cars ever more lavish. The redesigned 2007 Lexus LS460 deploys Denso's matrix infrared ray (IR) sensor, which it claims is the first of its kind, to detect the surface temperature distribution inside the vehicle cabin. The system's electronic control unit uses that data to automatically control temperature and airflow so passengers in both front and rear seats can be comfortable in their personally-selected climate zone. The sensor, one of about 40 in the vehicle, checks two points on the person and one on the seat.
