MS5534B Pressure Sensor and Its Height Measurement Applications

MS5534B is a pressure sensor with digital output. In this paper, the authors put forward a way to construct a height measurement system based on MS5534B pressure sensor, and discusses the system hardware and software design ideas in detail. Using LPC1114 microprocessor cooperate with the necessary peripheral interfaces to build the hardware framework of height measurement system, then developing software based on Lab VIEW virtual instrumentation development environment, finally analyzing the stability and accuracy of the MS5534B measurement data through an example, the test sites is in a 37-layer hotel, resolution of measurement system is 3%(at 33 layer), the maximum value of standard deviation is 0.53.
