Main cell phone sensor

Cell phone sensors can  identify which sensors the phone hardware supports and provide sensing tools that play an important role in our daily lives.

 

The distance sensor consists of an infrared LED light and an infrared radiation detector. It is located near the earpiece of the mobile phone. When we answer the phone, the distance sensor knows that the user is on the phone, and then turns off the display to prevent the user from influencing the call due to misoperation. As for the light sensor to detect the brightness of the environment, the software can automatically adjust the brightness of the display by using the data of the light sensor. When we play the phone at night, the sensor will sense the change of the surrounding environment, so the brightness of the display will be lowered accordingly.

 

The main function of the GPS position sensor is to receive the coordinates information of the satellite through the antenna to help the user locate. The principle behind it is not only applied to the mobile phone, but also widely used in all positioning devices.

 

When we look at photos and videos, we sometimes need to switch screens. At this time, the effect of the gravity sensor is reflected. It can switch between the horizontal and vertical screens according to the change of the direction of the mobile phone. In addition, the photos need to be switched, and some Gravity sensing games, all of which involve the participation of gravity sensing sensors. The gyro sensor is a necessary component for some inductive games. It is with this sensor that the interaction of mobile games has revolutionized, and the user feedbacks the game in combination with the multi-faceted operation, not just the game. Just a simple button.

 

The use of pneumatic sensors is relatively small, and changes in air pressure can cause changes in resistance or capacitance measurements. Generally, GPS can calculate your position, but for some height changes, you need a barometric pressure sensor to measure. In addition, when some outdoor applications need to measure the air pressure value, the mobile phone with the air pressure sensor can also come in handy.

 

The heart rate sensor is more common in the wearable device, but the application on the mobile phone is generally set at the back of the mobile phone. The principle is to convert the heart rate by converting the finger to the corresponding data by the high-brightness LED light source.
