Aqara FP2 is a next-generation presence sensor using 60GHz mmWave radar instead of traditional PIR. Core advantage: detects people sitting still reading, people lying down watching TV, or people sleeping in bed — scenarios where PIR fails due to lack of motion.
Common applications: (1) Auto-turn off lights when the room is truly empty (reduces lighting electricity by 30-50%); (2) Trigger HVAC by zone in open-space offices; (3) Fall detection for elderly rooms (optional — alert via Aqara Home app). Integrates with Apple Home / Google Home / Aqara Home via M3 hub.
Note: mmWave does NOT penetrate walls — only detects within the room where the sensor is placed. Privacy by design — NO camera/microphone used, only edge-processed radar data.

Câu hỏi thường gặp
- Is mmWave harmful to health?
No. FP2 emits very low power ~1mW (compared to phones 250mW, WiFi 100mW). Complies with FCC + IC + CE EMF international standards. The 60GHz frequency is absorbed by air within a few meters and does not penetrate the body like X-ray.
- Can it distinguish between pets (dogs/cats) and humans?
There are limits. The FP2 classifies based on radar reflection size — small dogs <10kg are usually filtered out, large dogs (Husky, Labrador) may trigger it. Cats are almost always filtered out. Adjust sensitivity in the Aqara Home app.
- Can it be integrated with the Crestron villa system?
Has via Matter bridge. FP2 exposes presence + lux via Matter → Crestron Home OS reads as standard sensor. Hybrid pattern Aqara (sensor + small device) + [Crestron (lighting + AV)](/thuong-hieu/crestron/) reduces cost by 40-60% compared to full Crestron.
