sensor(国外英语资料) Gravity sensor Mobile phone gravity sensing technology: the use of piezoelectric effect to achieve, simply speaking, to measure the weight of a piece of internal weight (weight and piezoelectric film as a whole), gravity quadrature in two directions of the component size, to determine the horizontal direction. Through the force sensitive sensor, the mobile phone changes the center of gravity when changing the gesture, so that the cursor position of the mobile phone is changed so as to realize the function of selection. Gravity induction refers to the mobile phone mobile phone built-in gravity rocker chip, support interface and functionality required to switch the shaking, rejection songs rejection screen, flip mute, whip switching video, is a very fun to use the function. Simple point is that gravity sensor, you should put the mobile phone in his hand up, you turn it 90 degrees, cross over, its pages will follow your focus automatically react, that page is turned 90 degrees, very humane. Basically, smart phones have built-in gravity sensors, and even some non smart phones are built in. Its common applications include playing with balance shots, surfing screens, reading novels, and the like Acceleration sensor An accelerometer is an electronic device that measures the speed of acceleration. Acceleration is the force acting on an object in the acceleration of an object, just like the gravity of the earth, that is gravity. The acceleration force can be a constant, such as a g, or a variable. Therefore, the range is larger than the gravity sensor, but it usually refers to the gravity sensor when the accelerometer is mentioned in the handset, so the two can be considered equivalent. Orientation sensor A direction sensor is a device that is mounted on a cell phone to detect the direction in which the handset is in itself, rather than the usual compass function. The direction detection function of the mobile phone can detect that the mobile phone is in the
