There’s a chip on the Galaxy S III called the STMicroelectronics LSP331AP, which is a pressure sensor. STMicroelectronics has decided to explain it to us, since it’s their new generation of pressure sensors. The chip is piezoresistor-equipped that uses pressure to track altitude. Even though it’s just a chip in a cell phone, it’s accurate enough to tell when you’re traveled between two floors. It can also work between 32,800 feet above and 5,900 feet below sea level. This has a lot of possibilities of course, including use in Google Maps’ indoor navigation (like mall maps) and sports like skydiving. Let’s hope these sensors go mainstream, and Samsung, thanks for pioneering them.
