A121 Smart Presence Reference Application User Guide
Technical guide for the A121 Smart Presence Reference Application, featuring multi-zone detection, fast/slow motion analysis, and resource usage for the XM125 module.
Overview
This user guide details the A121 Smart Presence Reference Application developed by Acconeer. It describes an algorithm that divides a radar detection range into multiple zones to identify and track presence. The application utilizes the A121 pulsed coherent radar sensor to detect both fast and slow motions, prioritizing responsiveness through specific filtering constants. The document provides comprehensive configuration parameters, including frame rates, sweep settings, and detection thresholds. Additionally, it outlines hardware resource requirements for implementation on the XM125 module, specifying memory footprints of approximately 85 kB Flash and 13 kB RAM, and provides power consumption data for various operating presets.
