Efficiency testing, Barometer sensor, Smartphone, Liquid pressureAbstract
In this paper, we presented results of the performance of barometer sensors and pressure measurement applications on iPhone 8 (Barometer Plus and Bar–o–Meter–Altimeter & Barometer applications) and Samsung Galaxy Note 9 (Barometer Plus and Physics Toolbox Sensor Suited applications) to measure the pressure of water (W=1.000x103 kg/m3) and sprite (S=1.067x103 kg/m3). The research results found that, the Barometer sensor and application on iPhone 8 can be measured precisely the water pressure more than sprite. Moreover, Samsung Galaxy Note 9 can be measured precisely the sprite pressure more than water. The percent errors of liquid pressure measured both iPhone 8 and Samsung Galaxy Note 9 have been less than 1. Conclusion that, the barometer sensors and pressure measurement applications on iPhone 8 and Samsung Galaxy Note 9 have been high efficiencies and precise in measuring liquid pressure. In application, the barometer sensors both on iOS and Android smartphones can been used measuring the pressure of liquid flow through the pipe in many dimensions to find the liquid force per cross–sectional area.
