Smartphones nowadays provide lot of exciting features which provides lot of easiness in our lives. Due to presence of all the important features, now you don’t have to carry things like personal digital assistant (PDA), camera or GPS device with you as they are available in smartphones.

But these tasks have to be done by sensors. We will provide you information about these sensors in the smartphones at this page.

Global Positioning System (GPS)

GPS system provides information about your location due to its connection o various satellites simultaneously. A GPS unit is present inside the phone that helps you find your location in any part of the world after receiving signals from satellites. It operates without using mobile data through which you can get your location even in the absence of signals.

This feature has few shortcomings as it will not work properly in heavy rainy conditions or if you are present underground or at a place with thick walls. Secondly, it will put extra load on your battery or which you should only enable it when it is necessarily required.

Magnetometer

This sensor locates the location of your mobile phone by measuring the magnetic field. It tells the north direction like other magnetic devices. Sensors perform their job by change in voltages. In metal detectors, magnetometers detect magnetic field after which they raise alarm.

The sensors start working after having compass mode in your smartphones and they are effective in the absence of GPS system. The proper working of magnetometer requires GPS and accelerometer.

Accelerometer

At the time your phone is not connected to your shoes, it can measure your steps by measuring axis-based motion sensing. Accelerometer is the main sensor used in AR (augmented reality) apps because it can inform about phone pointer’s direction. It is also used for speed you see on Snapchat due to its ability to measure your acceleration.

Maximum activity of the sensor is achieved with the combination of other sensors like microscopic crystal structure.

Gyroscope

In 2014, this sensor achieved fame in the phone industry due to its assistance to accelerometer in detecting the phone easily. 360 degree panoramas can also be stitched together with the help of gyroscope. Finding the altitude of the aircraft is the main reason these sensors are present in planes.

Few more Sensors

Air pressure of the room is detected by barometers which helps them to find weather changes. When the phone is near to an object or your ears, the screen is turned off by proximity sensor. The sensor is helped by LED and light detector. Ambient light sensor is another such sensor which detects the light levels around you and then adjusts the brightness of the screen accordingly. Adaptive brightness feature is provided in the smartphones through light sensors.
