5 Basic Sensors of Smartphones: From Rotating the Screen to Automatic Brightness Control
You must have noticed that when talking to someone on the smartphone, the screen light turns off automatically, while when you rotate the phone from landscape to portrait or portrait to landscape mode by turning on auto rotation, the aspect ratio of the screen also changes. goes. Have you thought about how this happens?
Nowadays smartphones are launching with many sensors but what are those find out below
1.Proximity sensor
This sensor is located in the upper part of the smartphone near the selfie camera. Usually, when you move the smartphone to the ear to make a call or make a call, this sensor automatically turns off the light of the smartphone’s display.
2.Accelerometer and gyroscope sensor
This sensor detects the direction in which the smartphone is rotating. Whenever we want to watch a video in landscape mode instead of smartphone portrait mode, then with the help of this we can watch the video on full screen. For this, as soon as we rotate the smartphone in landscape mode, the orientation of the video playing in the phone also becomes landscape.
It is called accelerometer and gyroscope sensor because two sensors are needed for rotation in a smartphone, in which the accelerometer controls its linear acceleration and the gyroscope controls the speed of its rotational angle.
3.Biometric Sensor
With its help, the security of the smartphone is maintained. The fingerprint sensor works through this sensor. This sensor takes data by scanning the thumb or finger entered in the smartphone. The second time the same thumb or finger is placed near this sensor, this information present earlier identifies the correct thumb or finger.
4.Ambient Light Sensor
This sensor not only adjusts the brightness of the smartphone’s display according to the light, but also helps in automatically increasing or decreasing the brightness of the display. All today’s smartphones support auto brightness control. Ambient light sensor is given for this in all these smartphones.
5.GPS sensor
You must know about this sensor. GPS means, Global Positioning System is the navigation system of America. India has a Navic Navigation System but it is being used in very few phones.
Through this sensor, it helps to know the location of the device. This sensor can connect with many types of satellites to tell where you are at the moment?
