The G-sensor (Gravity sensor) is generally defined as a motion sensor that is used for determining the changes in motion. This sensor is implemented in various places; even in smartphones, the G-sensors are installed. Whenever the smartphones are tilted to a certain angle, the screen gets changed and this is the function of the g-sensor. This G-sensor can also be used in the night vision technology.
In the night vision technology, the G-sensors are used for detecting the motion of the path. Any variation and obstacle within the paths are detected easily with the G-sensor and these obstacles are also informed to the drivers with higher efficiency. Mostly, the g sensors are built with camcorders fixed within the vehicles and in security cameras.
