The G-sensor (accelerometer) is used in mobile electronics to measure the position of a device in space, which makes it possible to expand the functionality. The technology makes it possible to carry out more convenient equipment control.
Principle of operation
The accelerometer itself is a small module or device that measures the acceleration of an object, acquired when the apparatus is displaced relative to the zero axis. Technically, the G-sensor measures the projection of the sum of all forces applied to the device's body, except for gravity. Simply put, the sensor allows you to measure the level of inclination of the phone, according to which the software of the device determines the location of the device in space and implements the functions necessary for use.
G-sensor and electronics
Thanks to the G-sensor, a number of useful functions are realized in mobile electronics. For mobile phones and tablets, the G-sensor allows you to activate the function of rotating the screen from vertical to horizontal mode for more convenient two-handed operation of the device. In car DVRs, the G-sensor records sudden braking, acceleration, turns and drifts. In the event of an emergency, the DVR starts recording video in order to fulfill its function and record the fact of the accident. In game consoles, the accelerometer is used to control the gameplay using controller turns. This feature allows you to improve the gameplay and make it more active and interesting.
At the same time, the user of the controller with the G-sensor is not required to press additional buttons to perform actions by the game hero.
Information carriers
Accelerometers are widely used in the manufacture of hard drives that store information. The G-sensor allows you to activate a special mechanism to protect the device from damage. When you change the position of the media in space, the hard drive head parking system is activated, which prevents the loss of important data in the event of a fall. As soon as the hard drive stops dropping, the media readheads automatically return to their original position.
Also, G-sensors are used in the device of inclinometers, which are used to measure the angle of inclination of necessary objects in the construction of structures, boreholes, architectural structures, etc.
Navigation systems
The accelerometer is one of the important components of navigation systems. With the help of the device, you can get the necessary coordinates and speed of movement of the object. G-sensors are used not only in conventional GPS systems, but are also used in the installation of navigation in airplanes, rockets and other aircraft. Geolocation using an accelerometer is used on ships and submarines.
