Micro Electro Mechanical System (MEMS) based Pressure Sensor in Barometric Altimeter

-Barometer is a well-organized tool for determining atmospheric pressure. The altimeter is a tool which calculates the vertical distance in accordance with a reference level. The barometric altimeter, computes the altitude according to the atmospheric pressure. Accuracy and size are the major issues in altimetry. On the other hand the present day altimeters employing conventional pressure sensors consume more floor space and provide very less accuracy. To resolve this problem, in this paper implemented a Micro Electro Mechanical System (MEMS) based pressure sensor in the design of barometric altimeter. MEMS are a class of systems that shares the existence of micro machined parts having both electrical and mechanical components incorporated on a single chip. MEMS pressure sensor guarantees higher degree of accuracy and reliability. These MEMS based barometric altimeter system operates with high sensitivity in the pressure. A temperature sensor is interfaced with the system so as to implement the dynamic temperature profiling approach as an attempt to eliminate the temperature dependent errors prevailing in the present day standard temperature profiled altimeters. MEMS based Barometric Altimeter is implemented using the following two modules: Embedded Module and Simulation Module. Even though the size of the MEMS based Barometric Altimeter is reduced, it provides more accuracy. ——————————  ——————————
