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