Smarter Motion Detection, Built for Everyday Automation
Traditional motion sensors can trigger lights unnecessarily or provide limited control over when automation runs.
The SONOFF SenseGuard Motion Gen2 combines fast PIR motion detection with an independent ambient light sensor, allowing your smart home to react to both movement and actual light conditions.
Set the sensor to trigger lights only when motion is detected in darker conditions, create automated scenes, or use unexpected movement to activate compatible security devices and notifications.
With Zigbee 3.0 connectivity, adjustable detection intervals, wide-angle coverage, and up to 3 years of battery life, SenseGuard Motion Gen2 makes everyday automation more responsive while keeping installation simple.
Why Choose the SONOFF SenseGuard Motion Gen2?
Choosing a Zigbee motion sensor is about more than simply detecting movement. Accurate light sensing, reliable coverage, flexible automation, and low maintenance all matter.
SenseGuard Motion Gen2 combines:
Fast PIR motion detection for responsive smart scenes
Independent lux sensor for accurate ambient-light-based automation
Adjustable 5–60 second detection interval to reduce unnecessary activations
120° sensing angle with up to 6m detection range
Up to 3 years of battery life from a CR2477 battery
Flexible magnetic, adhesive, or standalone placement
Built around the Zigbee 3.0 standard, the SNZB-03PR2 is designed to integrate into compatible smart home environments and support more intelligent automation.
