The Error Analysis of Barometric Altimeter for Internet of Things
This paper introduced the composition of barometric altimeter used to measure the height of the suspended platform for Internet of Things, and the principle of barometric altitude transformation algorithms.Through the analysis of the principle of the barometric altitude algorithm, we can get the main reasons which lead to the principle error of barometric altimeter.The pressure measured changed with the temperature, which lead the height from the pressure-height formula error.In order to make this error decrease to the least, a method by correcting the temperature measured was put forward, which improved the accuracy of the pressure-height formula and barometric.
