Smartphone, iPad and tablets are becoming popular day by day and many new features are getting incorporated everyday. Almost every electronics manufacturer is trying their products in market to due demand of these products in society. Samsung, Apples are the leaders in this category. There are some others cheap manufacturer in India like Micromax, LAVA etc. They are providing almost similar specification in just half of price value that branded manufacture are offering.

Most of us thinks large screen display, internal storage, RAM, camera are the only parameters for comparison. However they totally neglects powerful features like presence of sensors. Many of us either don't know their functioning and that's why they don't bother.

Due to introduction of some sensors like accelerometer and proximity sensors, the smartphones are really becoming very powerful and intelligent devices. You might have noticed, your mobile phone screen display turns off automatically as we bring it closer our ears during a calls. This happens due to presence of proximity sensors present in your smartphone. Its works like when mobile phones is very close to human ear, especially during a call; normally people don't use screen display and to avoid any unwanted touch the display and touch gets de-activated. Its also saves your battery in many cases. Like suppose you are far from your mobile and the screen automatically turns off.

All these functionality somehow depends on the sensors. Sensor like accelerometer is also much useful as it takes decision based on movements of your mobile. The screen of your smartphone automatically turns from portrait to landscape mode, while playing videos. This is due to the presence of accelerometer which provides you better user experience.

Accelerometer sensor is also known as motion sensor, as it has been extensively used in many cars racing games and many other tilting games.

Some other sensors worth mentioning are GPS (global position system), Ambient light and Compass. As you all must be knowing GPS is used for tracing once location extensively used for navigation purpose in maps. While Ambient light saves battery of your smartphone by turning of screen and keypad display light when not in use or idle conditions. Compass sensor is used for finding the north south direction as all of us know.

If you found any other sensor worth mentioning, then you can comment below.
