The MEROSS presence sensor delivers higher accuracy than typical detectors thanks to dual technology: passive PIR and 24 GHz millimeter‑wave radar. It reliably detects not only movement but also a person’s stationary presence, reducing false alarms from shadows or household appliances. The built‑in light sensor helps intelligently control lighting based on ambient conditions. With Matter support, you can easily connect it to HomeKit, Google Home, Alexa, and the Meross app; local mode ensures fast responses and privacy (a hub is required for Matter).

The practical swiveling base with tilt (360°/180°) lets you precisely aim the sensing zone. Motion detection works up to 12 meters and presence is reliably recognized up to 6 meters. Discreet installation is easy thanks to cable routing and the included accessories. Use it to automate lights, activate a bathroom fan upon presence detection, or turn off the air conditioner when leaving the room.

• Higher accuracy: the PIR + 24 GHz mmWave combination minimizes false alarms.
• Presence detection: recognizes a person even without visible movement.
• Lighting automation: the light sensor adapts scenes to current conditions.
• Wide compatibility: Matter for HomeKit, Google Home, Alexa, and the Meross app.
• Privacy and fast response: local operation without the need for cloud.
• Flexible mounting: 360°/180° base, range 12 m (motion) and 6 m (presence).
