The SONOFF SNZB-03PR2 is a Zigbee PIR motion sensor designed for smart indoor automation, lighting control and home security scenes. It detects movement quickly and helps connected devices respond automatically when motion is detected. The sensor is suitable for hallways, living rooms, bedrooms, kitchens, offices, storage rooms, stairways and other indoor areas where reliable motion-based automation is needed.
With responsive PIR infrared sensing, the SONOFF SNZB-03PR2 can detect motion within a short time and trigger smart scenes such as turning on lights, sending app notifications, activating alarms or starting compatible camera recording. This makes it useful both for everyday convenience and for home security automation.
The adjustable cooldown time allows users to customize the detection interval from 5 to 60 seconds. This helps reduce unnecessary repeated activations and makes automation smoother. For example, users can choose a shorter interval for high-response areas or a longer interval to avoid frequent triggering in rooms with regular movement.
The built-in independent lux sensor allows the device to detect ambient light levels more accurately. This makes lighting automation more intelligent because lights can be triggered not only by motion, but also by the brightness of the room. Users can create rules where lights turn on only when movement is detected and the environment is dark enough.
The sensor can record illumination history for up to 6 months, helping users understand lighting changes in their home environment. This information can be useful for creating more accurate lighting schedules, adjusting automation conditions and improving energy-efficient smart home control.
The SONOFF SNZB-03PR2 provides a 120° detection angle and a detection distance of up to 6 meters. This wide coverage helps monitor larger indoor areas and reduces the chance of missed movement. It is suitable for entrance areas, corridors, open rooms and other spaces where a wider sensing angle is helpful.
Flexible installation makes the sensor easy to adapt to different spaces. It can be placed on a surface, installed with adhesive, mounted magnetically or fixed with screws depending on the selected setup. The sensor head can be adjusted to aim the detection area more precisely, helping avoid unnecessary triggers from pets, walkways or areas that do not need monitoring.
The pet-friendly installation option allows users to position the sensor in a way that reduces unwanted detection caused by small pets. By adjusting the direction and installation height, the sensor can focus on the desired movement area and support more stable automation in homes with animals.
The SONOFF SNZB-03PR2 communicates using Zigbee IEEE 802.15.4 and requires a compatible Zigbee gateway for smart control. After pairing with a supported hub, it can be used for app-based automation, smart scenes, security alerts and integration with compatible smart home platforms.
The sensor can also work with Apple Home through a compatible Matter Bridge, depending on the selected SONOFF Zigbee bridge solution. It can also be integrated with open-source smart home platforms, giving users more flexibility when building local or advanced automation systems.
Powered by a CR2477 battery, the SONOFF SNZB-03PR2 can provide long operation time for everyday use. With up to 3 years of battery life, it helps reduce maintenance and makes the sensor practical for locations where frequent battery replacement would be inconvenient.
With its compact white body, indoor design and reliable Zigbee connection, the SONOFF SNZB-03PR2 is a practical addition to smart homes that need responsive motion detection, intelligent lighting control and flexible installation. It helps automate daily routines, improve comfort and support energy-saving scenes across indoor spaces.
