product description 

Proximity sensors are used to measure the proximity or distance of objects. According to this feature 

of proximity sensors, proximity sensors are used in the fields of counting and automatic control. At 

present, the mainstream smart phones on the market contain proximity sensors.

In addition, proximity sensors can be used to sense the distance between the phone and the human body. 

The specific use is to turn on the proximity sensor during the call, so when the phone screen is close to 

the user's face, it will automatically sense the distance between the phone and the human body. When 

the value is less than a certain value, the screen will be turned off, and the user will no longer receive the 

event of touching the screen, which effectively prevents the occurrence of false touch events during the call.
