Tencent Digital News (Wang Yang) The reason why smart phones is called smart, mainly because it has the additional attributes of traditional communications equipment does not have. The powerful performance and integration of mobile SoC chips have enabled smartphones to gain greater computing power, but those sensors that are hidden behind their phones are those that enhance the user experience. What is a cell phone sensor? In simple terms, a sensor is a device or device in a cellphone that can be measured and converted to a usable output signal according to certain rules. These sensors are generally composed of sensitive components and conversion components. In this article, we do not say complex principle, explain profound theories in simple language to introduce the sensor application scenarios. Light sensor The light sensor can adjust the screen brightness according to the environment of the phone at the time, and some can freely control the light and shade of the button breathing lamp. For example, in a particularly bright outdoor, the screen will be automatically transferred to the brightest state, and when in the dark environment, the screen brightness will be reduced accordingly. distance sensor The distance sensor is generally used with a light sensor. When you place the phone in the handset position, the distance sensor measures the distance the phone is in your ear. This different measurement will trigger the corresponding function, such as off the screen or automatically lock the screen, the same can also be used with a variety of protective cover to use. Gravity sensor Today, mobile phones are getting bigger and bigger, and horizontal screens, once considered unnecessary, have long been popular. Usually when watching photos, videos, we usually cross the phone to operate. In some games, richer interactive controls such as balance balls, racing games and more can be implemented with gravity sensors. Accelerometer The concept of accelerometer sensors and gravity sensors slightly overlap, but in fact they are not the same. Acceleration sensor is measured in many dimensions, the main calculation of some instantaneous acceleration or deceleration action. Such as measuring the speed of mobile phones in the game can be triggered by the acceleration sensor special instructions. Some of the daily application of shaking song, flip mute, also used this sensor. Fingerprint sensor Fingerprint sensors have started to explode in smartphones since 2013. It can automatically capture user fingerprints, in order to achieve the purpose of privacy protection. But now with a fingerprint sensor phone is not just unlock the device, but combined with the mobile payment, including Apple Pay, Sumsang Pay, fingerprint sensors are based on the premise to interact.
