Sensor BMP280 Statistical Analysis for Barometric Pressure Acquisition

Abstract

AbstractBMP280 sensor is widely used to measure air pressure. Accuracy and precision are parameters used to indicate the performance of a sensor. This study examined the BMP280 sensor performance by measuring the air pressure on 15 sensors compared with BMKG devices as a reference standard. This measurement was conducted in BMKG class III Tanjungpinang from 20-22 May 2022. BMP280 Sensor performance analysis was performed using a statistical analysis one-way ANOVA method, Tukey test, linear regression, and root mean square error. Based on the results of one-way ANOVA, it is found that there is a BMP280 sensor that is different from the others. The Tukey test found that ID sensors 6 & 14 are not significantly different, ID sensors 1 & 4 are not significantly different, sensors 15 & BMKG are not significantly different, and sensors 3 and 9 are not significantly different. In addition, the results of linear regression and RMSE show an increase in the accuracy of the BMP280 sensor reading. Linear regression makes sensor measurement more accurate due to the small RMSE value.
