Smart Motion Sensor Sonoff SNZB-03PR2 (SenseGuard Motion Gen2) – Zigbee 3.0 Protocol, Adjustable Sensitivity & Detection Time, Battery Life up to 3 Years, Adjustable Mount Included

Description

Sonoff SNZB-03PR2 is the performance-optimised version of the PIR motion sensor in the Sonoff ecosystem. Designed to eliminate false alarms and triggering delays, the new model brings major improvements in energy management and configuration flexibility.

Thanks to the integration of the Zigbee 3.0 protocol, the sensor offers minimal latency when running local lighting and security scenes, while also relieving the home Wi-Fi network. The device comes with an adjustable magnetic/articulated bracket, allowing positioning on the wall or ceiling at any angle needed to cover the desired area precisely.

Note: This product uses the Zigbee protocol and requires a compatible Zigbee hub/bridge (e.g. Sonoff ZBBridge-P / Sonoff ZBBridge-U / Sonoff ZBDongle-E / Sonoff Dongle-M) to be connected to the network and controlled from the app. It does not work on its own over WiFi.

Key Features & Technical Advantages

• Adjustable Sensitivity and Distance: Allows the detection sensitivity to be set in levels (Low / Medium / High) from the app, adapting the coverage range to the size of the room and preventing accidental triggering by small pets.

• Adjustable Detection Time (Blind Time / Timeout): Unlike conventional sensors with a fixed waiting time, with SNZB-03PR2 you can adjust the reset time after motion is detected (from 5 seconds to 60 seconds), ensuring ultra-fast re-triggering or keeping the light on without annoying interruptions.

• Extended Battery Life (Up to 3 Years): Through strict firmware optimisation and the new-generation Zigbee chip, a single battery lasts up to 3 years, eliminating frequent maintenance.

• Wide Detection Angle & Adjustable Bracket: Offers a detection range of up to 6 metres and a coverage angle of 110°. The included ball-joint bracket allows 360° rotation and tilting of the sensor for pinpoint orientation.

• Native Smart Home & Open-Source Integration: Directly compatible with Sonoff hubs (NSPanel Pro, ZB Bridge-P/U, iHost), as well as universal open-source controllers: Home Assistant (via ZHA or Zigbee2MQTT), SmartThings, Hubitat and Amazon Echo (with built-in Zigbee hub).

Ways to Use It and Scenarios

1. Smart Hallway and Stair Lighting: Instantly switches on the LED strip or smart bulbs connected to a Sonoff relay (e.g. Sonoff BASICZBR3 or ZBMINI) the moment motion is detected in the corridor at night.

2. Local Security System: Arm the sensor when you leave home. In the event of an intrusion, the sensor triggers an audible alarm via the iHost / NSPanel Pro hub and sends a critical notification to your phone.

3. Energy Saving in the Bathroom or Office: Automatically switches off the light and extractor fan if the sensor detects no motion for 10 consecutive minutes in an unoccupied room.

Package Contents

• 1 × Sonoff SNZB-03P Gen2 motion sensor

• 1 × CR2477 battery (pre-installed / included)

• 1 × Adjustable mounting bracket (360° articulated base)

• 1 × 3M double-sided adhesive tape & Set of fixing screws

Practical use cases

• Mounted in the hallway or bathroom, it automatically switches the light on when motion is detected and off once the room is empty, with no switches.
• Used near the entrance to trigger a phone notification when someone approaches the door at night.
• Integrated into a security scene that activates an alert if motion is detected in the home while you are away.
