The Meross MS600 is a hybrid detection system incorporating both a 24GHz mmWave radar module and a traditional PIR sensor. This dual-element architecture is processed by an ESP32 chipset, which facilitates native Matter-over-Wi-Fi support for simultaneous integration with Apple Home, Amazon Alexa, and Google Home. Performance metrics show that the inclusion of an integrated light sensor allows for illuminance-aware logic, while the wired USB-C power requirement reflects the high energy demands of the radar and Wi-Fi modules.
Schematic analysis confirms that the device utilizes a 24GHz frequency, which provides the capability to detect micro-movements like typing or breathing. Due to the wave properties of this frequency, the sensor can penetrate thin partitions; consequently, the Meross application provides detection range settings to exclude interference from objects such as ceiling fans or occupants in adjacent rooms. Hardware specifications indicate a room-clearing cooldown period of approximately 5 to 10 seconds following the cessation of movement.
- Matter-over-Wi-Fi: Enables local control and cross-platform compatibility without proprietary hubs.
- Hybrid Logic: Combines PIR for rapid initial detection with mmWave for sustained presence monitoring.
- USB-C Power: Eliminates battery maintenance for high-bandwidth sensing operations.
The MS600 operates as a standard Wi-Fi client on the 2.4GHz band. While this removes the need for a Zigbee gateway, it increases the total client load on the local network infrastructure. The device is designed for permanent installation in areas where sedentary occupancy is frequent, such as offices or living spaces.
For users who prefer a battery-powered solution and can tolerate higher trigger latency, the Lafaer Wireless Radar offers similar mmWave capabilities in a cord-free format.
This unit is a high-integration node within the motion/presence sensors classification, emphasizing multi-protocol interoperability.
