Awinic's AW96103/AW96105 proximity sensor.
|
||
|
|
The specific absorption rate (SAR) is a metric that measures
|
||
|
|
the degree of absorption of electromagnetic radiation emitted by
|
||
|
|
wireless devices, such as mobile phones and tablets, by human tissue.
|
||
|
|
In mobile phone applications, the proximity sensor is primarily
|
||
|
|
used to detect the proximity of the human body to the phone. When the
|
||
|
|
phone approaches the human body, it will actively reduce the transmit
|
||
|
|
power of the antenna to keep the SAR within a safe range. Therefore,
|
||
|
|
we also refer to the proximity sensor as a SAR sensor.
