Useful Smartphone Sensors

®Accelerometer

Accelerometer is a hardware based sensor. Mainly this is a micro-mechanical device, it is an object, position, speed, vibration, That is, until you talk to your phone as it will protect you from unnecessary work. Far removed from the ear to the phone display, the lights will come back again. , etc. are used to measure. There are various kinds of accelerometer, including one-axis, two-axis or ti-axis. Between these types of accelerometer ti-axis accelerometer is very strong. It can easily understand the orientation of the phone. After turn on your phone accelerometer sensor if you tilt your phone to 'Landscape' or 'Portrait ' and hold, then it will vary according to your screen. Sometimes need to change the phone's orientation. For example, browsing the web, watch videos, play games, read books, or sent text .In this cases
'Landscape' mode is more comfortable than 'portrait' mode. Now we can easily switch modes for accelerometers welfare. Accelerometer have more popular uses. For example: Control
music system (Shake To Change), during gaming we can control by tilt without pressing any key / we can flipped off the ringer without pressing any key. In sum, accelerometer can understand our phone's orientation and it helps with the change to adapt to the new orientation
phone.


®Proximity sensor

Proximity sensor is very important for smart phones. This sensor is based on hardware .It is able detect how far or near your phone from anything. Proximity can understand how far your body from your phone by sense. When you take your phone to the ear, and the lights of the phone’s display is automated way so that your battery is low cost.
Not only due to the sensor active when you talk on will the phone if you inadvertently touch the screen of your phone not be a problem if it takes. That is, until you talk to your phone as it will protect you from unnecessary work. Far removed from the ear to the phone display, the lights will come back again.


Ambient Light Sensor

This is another hardware based sensor. Smartphone and tablet PC are used this sensor to adjust the display brightness. This sensor is used to create a variety of photo-cell, Which are sensitive to the photon .Where you will be able to catch up at the presence of light sensor.
When you go to a dark room or a closed dark environment sensor will reduce the brightness of your display and you can be clearly seen in the dark. It will save your device’s battery.

Again, when you go to a bright light in the environment, such as the light of the sun during the day or when it will increase your device's display brightness, the sun light or extra light during the day due to your display, you will not see well. The brightness of the sun over the course will require you to definitely see the light. Which smartphones has the option to
auto-brightness, ambient light sensor works with all
of them


Compass / Magnetometer / Magnetic Sensor

Simply speaking, the compass or magnetic poles of the earth, is related to sensors .This sensor is a kind of magnet or magnets are used, or the magnetic field interacting with the Earth's magnetic field and the direction of the point to the earth. Although primarily used for navigation of the magnetic sensor is being used quite a good way smartphones nowadays. This sensor is rarely used in cheap Smartphones. Which phones have navigation feature the only phones that can be observed in the presence of this sensor. In short, compared to the poles of the earth where you stand, this is the work of magnetic sensor.
