Product description
SONOFF SenseGuard Motion Gen2 – Advanced Zigbee Motion Detection for Smarter Automation
The SONOFF SenseGuard Motion Gen2 (SNZB-03PR2) is a next-generation Zigbee PIR motion sensor designed to deliver faster motion detection, smarter lighting control, and more efficient home automation. Combining adjustable motion detection timing, an independent ambient light sensor, wide-angle coverage, and flexible installation options, it helps create more responsive and energy-efficient smart home environments.
With support for Zigbee smart home ecosystems, long battery life, and detailed illumination history tracking, SenseGuard Motion Gen2 provides reliable motion monitoring while reducing unnecessary activations and improving automation accuracy. Whether used for lighting control, security automation, occupancy detection, or energy saving scenarios, it offers a versatile solution for modern smart homes.
Key Features
- Fast PIR motion detection with customizable cooldown settings
Equipped with a highly responsive PIR sensor that quickly detects movement and allows users to adjust the cooldown period between 5 and 60 seconds. This flexibility helps reduce unnecessary triggers while creating smoother and more reliable automation experiences. - Independent lux sensor for smarter lighting automation
The built-in ambient light sensor operates independently from motion detection, allowing automations to react not only to movement but also to actual lighting conditions. Create more precise energy-saving rules by activating lights only when movement is detected and ambient light levels are low. - Detailed illumination monitoring and history tracking
Store and review up to six months of illumination history data to better understand environmental lighting conditions and optimize automation settings over time. - Wide-angle coverage with reliable detection performance
A 120° sensing angle combined with a detection range of up to 6 meters provides broad room coverage and helps reduce missed movement events in daily use. - Flexible installation options for different environments
Install the sensor using adhesive mounting, magnetic attachment, or standalone placement. The adjustable sensor head allows precise positioning and helps avoid unwanted detections caused by pets or environmental activity. - Pet-friendly positioning flexibility
The movable sensor head allows the detection area to be adjusted according to room requirements, helping minimize activations caused by pets while maintaining effective human motion detection. - Long-lasting battery performance
Powered by a high-capacity CR2477 battery, the sensor can operate for up to three years under normal usage conditions, reducing maintenance requirements and battery replacement frequency. - Ideal for smart lighting, security, and automation
Perfect for motion-triggered lighting, occupancy-based automation, energy-saving scenarios, room monitoring, hallway illumination, and general smart home security applications.
No Intrusion Unnoticed. No Suspicious Move Missed.
When the sensor detects an intrusion, it instantly triggers a range of smart security scenes — sound a gateway alarm, push an app notification,
and start your camera recording. Set it once, and let your home guard itself.

1. What is the motion detection range and respond time?
It typically detects motion about 6 meters and has a horizontal field of view of around 120°, ideal for hallways, corridors, staircases, and entrances. It supports rapid detection, triggering linked actions in as fast as 5 seconds.
2. How good is the device's light detection capability?
The device has a built-in dedicated light sensor that can measure accurate lux values and includes a calibration function.
Different sensor orientations may cause inconsistent brightness readings. Please fix the sensor orientation and use the calibration function to adjust the brightness.
3. How can I use the device for light control?
The device itself allows you to set the lux value as a trigger condition in smart scenes, achieving an "auto-on at dusk" effect. In addition, light intensity can be combined with motion detection as a trigger condition to create an "auto-on at dusk with motion" effect, which is ideal for lighting corridors, staircases, and entrances at night.
4. Can I mount it on a ceiling or wall?
Yes. The sensor is designed for flexible mounting using magnetic attachment, screws, or adhesive. It can also be flush-mounted using an accessory (available in July 2026).
5. Will pets interfere with the device?
The device uses passive infrared (PIR) to detect motion via temperature changes. Pets with similar body temperatures (e.g., cats, dogs) may cause false alarms, but you can adjust the device's head orientation to avoid pet activity areas.
