It enables human presence and motion detection, as well as high-precision distance measurement. With configurable detection zones and sensitivity parameters, it offers excellent anti-interference capabilities. The module integrates an Arm Cortex-M4 MCU (STM32L431CBT6), allowing it to run user applications directly on the Acconeer RSS as an independent unit, or communicate with an external host controller via a register command protocol. Compact in size, low in power consumption, and easy to integrate, it is ideal for applications such as human presence detection, proximity sensing, non-contact triggering, and vital sign monitoring.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:center;color:rgb(0, 0, 0)\" align=\"center\"\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align:center;color:rgb(0, 0,
