Meross has introduced the MS605, a new battery-powered presence sensor that eliminates the need for a power cord during installation. The MS605 is powered by a single CR123A battery, offering up to three years of battery life, though this may be shorter in high-traffic areas with frequent sensor activation.
The MS605 features support for Matter over the low-power Thread protocol, allowing it to integrate with smart home ecosystems like Google Home, Apple Home, or Alexa without requiring a specific Meross hub. Unlike its predecessor that relied on Wi-Fi, the MS605 requires a Thread-capable hub in the household.
The sensor retains the articulated mounting plate from its predecessor, enabling flexible angling up to 90 degrees and full 360-degree rotation. It also boasts an IP67 waterproof rating, enabling outdoor use. The MS605 is equipped with a combination of light, passive infrared (PIR), and 24GHz mmWave radar sensors to detect both moving individuals and stationary objects, while distinguishing between human presence and other moving entities.
While the battery-powered design offers convenience, the MS605’s detection range has been slightly reduced to 6 meters for motion and 4 meters for presence detection, down from the previous 12 meters and 6 meters, respectively.
