ANALISIS PERBANDINGAN AKURASI PADA SENSOR TEKANAN BMP280 DAN BME280

Abstract

Air pressure is the force exerted above the surface. The higher an area of sea level, the lower the air pressure. Many devices are used to measure air pressure, one of which is a sensor. Sensors are equipment used to detect a quantity that is converted into a large amount of electricity. A sensor, before use, the thing that must be known is how accurate the sensor is. In this study, we will calibrate two air pressure sensors. The sensors used are BME280 and BMP280. Calibration is done by comparing sensor reading data with Climatology and Geophysics Meterology Agency (BMKG). Based on calibration results, the BMP280 sensor is more accurate than the BME280. The results of the comparison of sensor data with BMKG data, namely BMP280, received a RMSE value of 0.16 hPa and BME280 of 2.25 hPa.
