Semtech PerSe (Person Sensing) Error Detection and Configuration
In SAR applications, Semtech SX9331 CAP sensor can detect whether a human body is approaching. When a human body is approaching or moving away, SX9331 sends an interrupt notification to the Host or DSP, and the Host or DSP decides whether to reduce the RF power to ensure that the human body receives The electromagnetic radiation received will not exceed the standard to ensure compliance with SAR regulations.
