How 60 GHz Radar Improves Low-Power Presence Sensing In IoT Devices

Battery-powered IoT devices must maintain room-level awareness without keeping their full sensing and processing chains continuously active. A duty-cycled architecture built around sensors that detect larger body motion and micro-motion allows smart thermostats, occupancy sensors, and security systems to monitor occupancy, track motion, and wake downstream hardware only when needed. This article reviews how 60 GHz frequency-modulated continuous-wave radar supports low-power presence sensing in I
