Purpose

This overview serves as the SmartHomeConcierge.ai master reference for mmWave Human Presence Detection technology. It provides a comprehensive summary of millimeter-wave (mmWave) radar sensing, occupancy detection, automation capabilities, supported applications, installation considerations, configuration options, and common troubleshooting categories used by SmartHomeConcierge.ai technicians when assisting customers and creating device-specific configuration articles.

Unlike traditional PIR (Passive Infrared) motion sensors that only detect movement, mmWave (Millimeter-Wave) radar continuously detects the presence of a person by sensing extremely small body movements, including breathing, posture changes, and slight hand or head movements. This enables lighting, HVAC, security, and automation systems to remain active while someone is quietly sitting, working, reading, or sleeping.
