摘 要：Two classic atmospheric pressure sensors MS5534C and BP5607 were introduced, due to the measurement sensitivity and resolution is different, performance in differential barometric altimeter system may be different. The experiments show that the two sensors both can distinguish be-tween floors in the differential barometric altimeter system and have a good measured highprecision. Yet, for BP5607 the elevation resolution is better than the MS5534C, the use of BP5607 is more flexible and so on. High-sensitivity, high-resolution pressure sensor in the field of location information services will have greater application space.
