Top sensors inside the smartphone you want to know
The document discusses the key sensors inside smartphones that enable their smart capabilities. It describes sensors such as the accelerometer, which senses device orientation; the magnetometer, which works with the digital compass to detect direction; the gyroscope, which maintains position and orientation; and the fingerprint sensor, which provides biometric authentication. It also mentions other sensors like the back-illuminated sensor for cameras, ambient light sensor for display brightness, GPS for location, proximity for detecting nearby objects, NFC for short-range connectivity, and more. All of these sensors collectively convert a normal phone into a smart device.
Mobile Sensors
The proximity sensor detects how close an object is to a smartphone's screen. It detects the position of a user's ear during calls to turn off the screen and save battery. This prevents accidental touches. It also detects signal strength and filters interference using beam forming. The ambient light sensor adjusts screen brightness based on light intensity to save battery life. The accelerometer senses orientation changes to adjust the screen from portrait to landscape. The compass uses signals from sensors rather than a magnet to determine direction. Gyroscopes maintain orientation and detect motion in six axes like roll and pitch using MEMS technology. The back-illuminated sensor captures more light for photos. Higher-end phones have barometers for improved GPS accuracy and pedometers count
