SONOFF SenseGuard Presence Core 24GHz Zigbee Human Presence Sensor | SNZB-06P24

SONOFF SenseGuard Presence Core 24GHz Zigbee Human Presence Sensor (SNZB-06P24)

The SONOFF SenseGuard Presence Core (SNZB-06P24) is a high-precision 24GHz mmWave radar human presence sensor designed for reliable static and micro-movement detection. Unlike traditional PIR motion sensors, it can detect a person sitting still, working, or reading by sensing subtle body movements such as breathing. With 7 independently configurable detection zones, self-learning interference filtering, and a built-in ambient light sensor, it is an excellent choice for smart lighting automation, energy saving, and Home Assistant setups.

KEY FEATURES

• 24GHz mmWave Radar: Accurately detects human presence including micro-movements (breathing, slight limb movement)
• 7 Configurable Detection Zones: Detection area up to 4 meters divided into 7 independent zones that can be enabled or disabled individually
• Self-Learning Anti-Interference: Automatically filters out interference from fans, appliances, pipes, and other moving objects
• Ambient Light Sensor: Reports lux values for intelligent lighting control (only turn lights on when needed)
• Flexible Mounting: Strong magnetic base allows desktop placement, wall mounting, ceiling installation, or adjustable angles (360° rotatable head)
• Zigbee 3.0: Reliable local communication with low power consumption
• Home Assistant Compatible: Works with ZHA and Zigbee2MQTT
