Abstract

An air pressure gauge instrument has been successfully made using the Arduino Uno-based BMP280 sensor. This instrument was standardized by using a standard measuring instrument at the Central Bureau of Meteorology, Climatology and Geophysics (BMKG) Region III Tuban Bali. It was obtained that the calibration equation is y = 1.0022x - 1.8907 with a coefficient of determination (R2) of 0.99998. This shows that the instrument made has a high degree of accuracy and precision.
