A barometric pressure sensor is an absolute pressure sensor that is used to measure barometric pressure. The full-scale output can be calibrated in a number of different ways, but is typically 16 to 32 or 0 to 30 inches of mercury. Consult the Pressure Reference Chart to compare how the various pressure sensors reference pressure.
