Design of air pressure and height measuring equipment based on Arduino nano using BME280 sensor

This research has succeeded in designing air pressure and altitude measuring instruments based on arduino nano using BME280 sensor. The design of this tool uses the sensor as an input for parameter values ??of altitude. measurement results are displayed organic light emitting diode (OLED), which been processed by Arduino Nano. Sending HC-05 module. Calibrate parameters at Center Meteorology, Climatology Geophysics Region III Denpasar Vaisala PTB 330 digital barometer media chamber, while calibrate Google Earth reference . calibration two indicate that instrument a good level accuracy, 99.99% 99.98%. In addition, test suitability OLED output data application shows communication successful is accordance with match 100%.
