+description: |
+  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.
