Meross Unveils MS605: A Next-Generation Smart Presence Sensor
Developed from real user feedback, the MS605 isn’t just an update — it’s a complete rethinking of what a presence sensor can be. It directly addresses common frustrations such as false triggers, limited placement, and unstable connectivity, and breaks free from the constraints of wired power by adopting long-lasting battery operation with up to 3 years of lifespan. This truly wire-free design enables flexible installation in far more environments, further supported by a wide operating temperature range of –20°C to 60°C and IP67 waterproof and dustproof protection. The result is a new standard of precision, flexibility, and intelligence. It’s not just about detecting motion — it’s about understanding presence.
For a limited time, the MS605 is available at an introductory price starting from just $33.99 (EU) / $34.99 (US).
Why the MS605 Matters
Traditional motion sensors stop detecting when you stop moving. Users end up walking around waving their hands just to keep lights on. The MS605 solves this problem by understanding presence — even subtle micro-movements such as breathing — while delivering dramatically higher accuracy, flexibility, and privacy protection. With Thread and Matter now rapidly expanding across the industry, the MS605 arrives at the ideal moment: users want reliability, multi-platform compatibility, and a sensor smart enough to drive automations without frustration.
Executive Quote
“The MS605 represents our biggest leap forward since the MS600,” said Paper Ma, Head of Product at Meross. “Users told us they wanted accuracy without complexity, stability without wiring, and smart automations without false triggers. With Matter over Thread, triple-sensor fusion, and battery-powered IP67 protection, the MS605 delivers exactly that — reliable, intelligent presence detection for every home.”
Key Breakthroughs of the MS605
1. Rock-Solid Matter over Thread Connectivity
The MS605 leverages Matter over Thread for an ultra-stable, low-latency, and energy-efficient smart home experience. It’s a significant upgrade over the Wi-Fi-dependent MS600, offering broader integration with: Apple Home, Alexa, Google Home, SmartThings & Home Assistant. No Meross hub is required. (A third-party Thread border router is needed)
2. Unprecedented Detection Accuracy
-Triple-Sensing Fusion + Dual Detection Technology: Say goodbye to false alarms. The MS605 fuses radar (for micro-movements like breathing), PIR (to filter non-human heat sources), and a light sensor (for ambient-aware lighting) for absolute precision. It detects both motion and stationary presence with high accuracy, minimizing false triggers from “ghosting,” robotic vacuum cleaners, or wind. (Note: Alexa currently does not support the light sensor feature.)
– Detection Performance: Up to 4 meters stationary presence detection & Up to 6 meters motion detection.
– Adaptive Sensor Modes: Select from three modes tailored to your environment: Radar Mode: Ultra-high sensitivity for clean, stable environments / Radar + PIR Assist Mode: Balances precision and filtering to confirm human presence while reducing false triggers / PIR + Radar Assist Mode: Prioritizes energy efficiency in spaces with clear body-to-ambient temperature differences.
3. Multi-Zone Detection & Smart Scene Automation
– Seven-Range Control: A major upgrade from the MS600: Divide the 6-meter detection field into seven independent segments, each with its own adjustable blocking and activation function. With the Range feature in the Meross App, you can precisely fine-tune the detection area to match your space—focusing only where it matters while intelligently ignoring minor movements from plants, fans, or air conditioning.
– Multi-Zone Smart Scenes. The detection area can be split into three virtual sensors for smarter automation. Each zone can have its own presence/absence duration, enabling flexible scene control. Set up in the Meross App and use seamlessly on third-party platforms. (Support for SmartThings is pending future platform updates.
4. Self-Learning Intelligence. A context-aware AI engine learns your home’s unique patterns over time. It continually improves detection accuracy, reduces false triggers, and receives ongoing enhancements via Bluetooth OTA updates through the Meross App.
Hardware Upgrades at a Glance

MS605 vs MS600 vs Motion Sensors — What’s New?
Designed for Every Home
The MS605 is designed to fit your life, not the other way around.
· Flexible Installation — With a 90° foldable and 360° rotatable stand, it can be mounted on ceilings, walls, or corners with ease.
· Pet-Friendly Design — Stop false alerts from pets. Simply adjust the sensor’s angle to focus on upper-height movement. For stubborn cases, you can also invert it or apply a tape cover for precise signal blocking.
· Complete Privacy Protection — It includes no camera and requires no image or spatial scanning, ensuring your data stays private and local.
