A barometric pressure sensor measures pressure differences in the atmosphere. In automotive applications, this reading is used by the powertrain control module to regulate engine timing and fuel trim. Most barometric pressure sensors that can operate independently are usually placed on top of the firewall or the fender skirt's interior. Some devices are installed along with the manifold absolute pressure sensor or mounted on the intake manifold of the fuel system. One variation in barometric pressure sensors is the range of pressure levels these instruments can measure. The CS100 barometric pressure sensor manufactured by Setra detects fluctuations in atmospheric pressure between 600 to 1,100 millibars, while Vaisala's CS106 pressure sensor gauges pressure differences from 500 to 1,100 millibars.
Knowing what a barometer is or how to use it is pointless if you don't understand air pressure. Air pressure, or barometric pressure, is the measurement of how much air is above any one area at a given time. The more air, the more pressure that it exerts down on the space below.he air pressure at sea level is 14.7 pounds per square inch, or 1,013 hectopascals. The phrase a rising barometer means that air pressure is increasing, while a falling barometer indicates a drop in pressure. As the air pressure changes, the amount of oxygen present does too.
