The accelerometer is an electronic component that measures tilt and motion. She is also able to detect the rotational movement and gestures such as swinging or shaking a given electronic device of which it is part.
The most common use for this is to activate the automatic rotation of the screen on mobile devices when the user changes its orientation from portrait to landscape or vice-versa. Another modern application for the accelerometer is to control the music player of the mobile device with gestures or the simple swing of the device.
Accelerometers are also used to enrich the game controllers, navigating by tilting the device instead of pressing the keys.
Another feature of the mobile phone popular based on an accelerometer is to turn the screen down to let it mute. It allows the user to silence an incoming call, mute the alarm or pause the mobile music player simply by rotating the device down.
There are still several other functions, all using this small special sensor and optimizing the use of your device.
How it Works the Accelerometer?
Before we can say that the accelerometer if the smartphone does, we need to understand the basics of what an accelerometer does in general. The transducer is a device that can measure the force of acceleration caused by the force of gravity or by movement. An accelerometer can therefore measure the speed of movement of an object to which it is connected. This is the job of the accelerometer in the iPod + Nike used in running shoes for example. The sensors on glass can tell if the shoe they are in is moving (in the instant in which it is not, the device turns off) and, based on the amount of time that the shoe is on the ground in relation to the value of time is in the air, iPod can convert this information into an accurate measure of the speed at which the runner is moving.
Because an accelerometer senses movement and gravity,it can also detect the angle in which the action is to be performed. As an example: the user manipulates a controller. The controller contains accelerometers, solid-state, which can sense the tilt, movement and speed being applied, as well as the direction.
In a smartphone, the movement and tilt of the device is known by the sensors, so it can tell which way the screen is being taken. This allows you to automatically adjust the visual output to make it suitable for the direction of the screen. This way, you can view lists with the screen vertically and watch videos with the screen sideways, denre several other things that we have already described above.
Every Device Has an Accelerometer?
In general, this type of sensor is present in intermediary devices, or top of the line. Entry models hardly has this type of mechanism, but there can be exceptions. A way to check if your device has an accelerometer or not is to look at the specifications of your device on the site GSMArena. Just look for the sensor in the specifications and ready.
We hope to have you helped to remedy this question and to understand a little more of the workings of smartphones with this article.
