Upgrade your home security and automation systems with the Sonoff SNZB-03 Zigbee Motion Sensor. Designed for precision and reliability, this compact sensor uses advanced Passive Infrared (PIR) technology to detect human movement and send real-time alerts. Whether you want to automate lighting, improve energy efficiency, or safeguard your home while away, the SNZB-03 integrates seamlessly with most Zigbee 3.0 hubs to enhance your smart environment.

Key Features

1. Accurate PIR Motion Detection

   • The sensor intelligently recognizes motion within its coverage area, quickly distinguishing between normal household movements and inactivity. This ensures reliable performance for security and automation tasks.

2. Zigbee 3.0 Connectivity

   • Enjoy stable, low-power operation and rapid response times with Zigbee 3.0. Minimize Wi-Fi congestion and benefit from mesh networking, which enhances range and reliability when used with compatible Zigbee devices.

3. Real-Time Alerts & Automation

   • Receive instant notifications on your smartphone when motion is detected—perfect for monitoring entry points or high-traffic areas. Pair it with smart lights or cameras to create tailored automations and scenes that activate only when needed.

4. Energy-Efficient Battery Operation

   • The device is designed for extended battery life, reducing the frequency of replacements. A low-battery indicator ensures you’re informed when it’s time to replace power cells.

5. Compact & Discreet Design

   • With its minimalist form factor, the SNZB-03 can be easily placed on walls, ceilings, or corners. Its unobtrusive appearance blends into most interiors without drawing attention.

6. Easy Installation

   • Mount the sensor using the included adhesive pad or screws. Once powered, pair it with your Zigbee hub through the recommended app (eWeLink or another compatible Zigbee platform) for immediate use.

7. Versatile Placement

   • Ideal for hallways, entryways, garages, or any location where motion detection is required. Place multiple sensors around your home or office to build a complete motion tracking system.

How It Works

1. Power Up: Insert the required battery into the sensor.

2. Pairing: Use your Zigbee hub’s companion app to detect and connect the SNZB-03 quickly.

3. Placement: Attach the sensor at the desired location, typically 1.8–2 meters above the floor for optimal coverage.

4. Configuration: Set up custom alerts, schedules, or triggers—such as turning on lights when someone enters a room or sending push notifications if motion is detected while you’re away.

Typical Use Cases

• Security Monitoring: Get immediate alerts if motion is detected in restricted areas or when you’re away.

• Smart Lighting: Automate lighting in hallways or bathrooms to conserve energy—lights turn on only when someone is present.

• Home Automation Scenes: Integrate the sensor with cameras, alarms, or other smart devices to create comprehensive routines that suit your daily life.

• Pet Monitoring: Keep track of pet movements within the home, or configure rules to minimize false alarms triggered by smaller animals (where supported).
