Frequency60-64 GHz FMCW
Detection range0.3-8 m presence, 0.3-12 m motion
Field of view120° horizontal × 60° vertical
OutputsPresence, motion, distance, respiration rate
Overview
Conventional PIR needs movement; FMCW radar measures micro-motion, including breathing, so lights and HVAC stay on when someone is reading at a desk. Because it senses through non-metallic enclosures, the module can be potted inside a luminaire or a control panel.
Key features
- 60-64 GHz FMCW with micro-motion and vital-sign output
- Presence detection to 8 m, motion to 12 m
- 120° × 60° field of view, ceiling or wall mount
- Works through plastic and glass: no cut-out needed
- UART, RS485 and GPIO interfaces; 3.3 V or 12 V supply
- 0.35 W typical, no image sensor and no privacy issue
