Different types of mobile sensor and their functions
Accelerometer sensor in mobile is used to detect the smartphones orientation weather it is in portrait or landscape orientation. Accelerometer sensor provide comfortable viewing experience for user.
2. Ambient Light Sensor:
This sensor helps mobile to adjust screen brightness automatically through detecting the surrounding light. When the auto brightness mode is on in mobile the sensor works for adjusting screen brightness.
3. Barometer Sensor:
Barometer is used to measure atmospheric pressure and barometer sensor also assist GPS in smartphones to know exact location of device by providing instantly the altitude data. Some weather apps use barometric sensors.
4. Gyroscope/ Gyro Sensor:
Gyro Sensor provides the accuracy for smartphone to detect precisely the direction, rotation, orientation of mobile. Many gaming apps use gyro sensor, the gyro scope enables mobile to get commands by tilting or moving mobile in up-down, left-right direction.
5. Hall Sensor:
Hall sensor in mobile enables mobile to close screen, or put mobile on ideal mode. It works by detecting magnetic field, mostly it is used when there is flip cover on mobile, that enables phone to act according to flip cover.
6. Magnetometer Sensor:
Magnetometer is useful in navigation, maps, direction, compass of smartphone. As magnetometer sensor detects the magnetic field and easily locates the north pole direction. Magnetometer is also capable of detecting metal.
7. Proximity Sensor:
Proximity sensor is mainly useful in detecting the distance of mobile from the skin. Most of touchscreen mobiles are laced with proximity sensor to avoid accidental operating of touchscreen during calls, as the mobile is held near ear of user the mobile puts touchscreen on standby mode with help of 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 user and in case of overheating of device shutdown mobile to prevent it from further damage.
Biometric sensors are used to enhance mobiles security through using different biometric measures to lock and unlock mobile devices. Fingerprint recognition, face recognition, IRIS eye scanning, etc. Biometric sensors provide more security to mobile devices in 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 near by 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 of battery support for NFC device to work. Mainly this is used to share videos, photos, make payments in much secure way as both devices are supposed to hold very near to each other.
