Pressure sensor providing advanced altitude information for smartphones Initially, Samsung obtained location information using accelerometers, gyroscopes, and magnetometers. To improve this, the Galaxy S4 was equipped with a pressure sensor. The pressure sensor provides today's accurate indoor location information. Around the same time, Apple also equipped the iPhone 6 with a pressure sensor. Today, many portable products are equipped with pressure sensors. Altimeters generally use absolute pressure sensors. They measure the phenomenon that atmospheric pressure decreases as altitude increases, using a vacuum as a reference. These two are related by the following equation. <For more details, please see the detailed page>
