Different sensors in mobile phones play a vital role. Today’s smartphones are laced with many advanced features combining many small but highly functioning components, all together these tiny components make today’s mobile devise smarter. Many tiny mobile sensors have some distinct functions to equip your mobile, have you ever thought of, how mobile can automatically adjust screen brightness or on the torch when shake or shows the exact location on maps, etc., all these is done with the help of different small tiny sensors located in your smartphone. Here is brief knowledge about all the major and most useful sensors in mobiles.
Types of sensors in mobile
- Ambient Light Sensors
- Hall Sensor
- Proximity Sensor
Accelerometer sensor in mobile is used to detect the smartphone’s orientation whether it is in portrait or landscape orientation. The accelerometer sensor provides a comfortable viewing experience for the user.
2. Ambient Light Sensor:
This sensor helps mobile to adjust screen brightness automatically by detecting the surrounding light. When the auto-brightness mode is on in mobile the sensor works for adjusting screen brightness.
3. Barometer Sensor:
A barometer is used to measure atmospheric pressure and a barometer sensor also assist GPS in smartphones to know the exact location of the device by providing instantly the altitude data. Some weather apps use barometric sensors.
4. Gyroscope/ Gyro Sensor:
Gyro Sensor provides the accuracy for the smartphone to detect precisely the direction, rotation, the orientation of mobile. Many gaming apps use gyro sensor, the gyroscope enables the mobile to get commands by tilting or moving mobile in an up-down, left-right direction.
5. Hall Sensor:
Hall sensor in mobile enables the mobile to close the screen, or put mobile on ideal mode. It works by detecting a magnetic field, mostly it is used when there is a flip cover on mobile, that enables the phone to act according to the flip cover.
6. Magnetometer Sensor:
A magnetometer is useful in navigation, maps, direction, the compass of the smartphone. As magnetometer sensor detects the magnetic field and easily locates the north pole direction. A magnetometer is also capable of detecting metal.
7. Proximity Sensor:
A proximity sensor is mainly useful in detecting the distance of mobile from the skin. Most touchscreen mobiles are laced with proximity sensor to avoid accidental operating of touchscreen during calls, as the mobile is held near the ear of the user the mobile puts touchscreen on standby mode with help of a proximity sensor.
Today smartphones have inbuilt thermometer sensors, with the help thermometer sensor mobile is enable to monitor the temperature of mobile and environment. This helps to display the temperature to the user and in case of overheating of device shutdown mobile to prevent it from further damage.
9. Bio metric Sensor:
Bio-metric sensors are used to enhance mobiles security by using different bio-metric measures to lock and unlock mobile devices. Fingerprint recognition, face recognition, IRIS eye scanning, etc. Bio-metric sensors provide more security to mobile devices in a more convenient way.
10. NFC (Near Field Communication):
NFC sensor is available in some smartphone, with the help of this sensor the mobile can communicate with nearby NFC device by bringing both devices within 4-inch range. Each device shares a high range frequency to communicate with each other through encrypted data sending. There is no need for battery support for the NFC device to work. Mainly this is used to share videos, photos, make payments in a much secure way as both devices are supposed to hold very near to each other.
