The Meross Presence Sensor combines millimeter-wave Doppler radar technology with infrared motion sensors, creating a dual-detection sensor capable of recognizing biological movements, subtle motions, and presence status. Additionally, the product is equipped with a light sensor that can detect changes in ambient brightness in real-time. Once a change in biological movement or ambient brightness is detected, the sensor will promptly transmit the information to the Meross system or Matter platform. With Matter integration, the device can support all major platforms, like Apple Home, Google Home, Amazon Alexa, Samsung SmartThings and so on.

More Powerful Sensors and Algorithms: The Meross Presence Sensor, using dual detection technology, combines PIR and millimeter wave radar, offering significant advantages over single-detection sensors. This advanced technology allows the sensor to accurately detect changes within a space, detecting not only motion but also user presence (even without any motion). Dual detection technology detects both motion and stationary presence with high precision, minimizing false alarms from sources like “ghosting,” “vacuum cleaners,” or “wind.” Enhanced with a built-in light sensor, it offers greater possibilities for lighting automation. Note: The Meross Presence Sensor is wired and requires continuous power.

Multi-Ecosystem and Local Support: The Meross Presence Sensor integrates seamlessly with multiple platforms through the Matter framework, including Meross, HomeKit, Alexa, and Google Home. This integration provides enhanced stability, lower latency, better privacy, and offline control compared to traditional methods. On the Matter platform, both presence and light sensors are displayed, simplifying automation setup.

Reliable and Privacy-Conscious: The Meross Presence Sensor uses millimeter wave radar technology to detect motion, including subtle movements, without generating “ghosting” effects. Unlike cameras, it doesn’t record images or collect data about your indoor environment, ensuring robust privacy protection.

Flexible Installation and Wide Coverage: The Meross Presence Sensor comes with an adjustable base that swivels 180° and rotates 360°, plus built-in cable management for easy setup. It offers a wide detection range of up to 12 meters (with presence detection effective up to 6 meters).

Versatile Applications: This sensor is ideal for a wide range of uses, including lighting, security systems, garages, doors, smart homes, smart hotels, and IoT setups. It’s perfect for any situation where detecting subtle movements, motion, or presence is important.

Effortless Smart Scenes: Keeping the lights on while reading but turning them off during the day; running the air conditioner while you sleep but turning it off when you leave the bedroom; activating the exhaust fan if you’re in the bathroom for over five minutes; turning on the ceiling light in the living room and the floor lamp by the sofa as you move around—all with a single device.

Ready-to-Use Kit: Includes 1 MS600 Presence Sensor (with adhesive mount for any home), 3 cable clips, 1 pet-proof shield, 1 power adapter, and 1 power cable (1.5m).
