The 2007 BMW X5 Sport Activity Vehicle is a high-tech showcase. One of its more unusual sensor systems is an Air Classification Module that prevents the intake of harmful combustion fumes like carbon monoxide and nitrogen dioxide. AppliedSensor of Warren, NJ, makes the module, employing a pair of sensing elements from Sensata Technologies, based in Attleboro, MA. The sensors work closely with a module in the air intake duct of the vehicle’s heating, ventilation and air conditioning system to temporarily shut down intake when fumes are detected.
