SONOFF PIR3-RF 433MHz RF PIR Motion Sensor – PIR3-RF | 433.92MHz Motion Detector, 8m Detection Range, Smart Scene Trigger, RF Bridge Required.
Overview:
• SONOFF PIR3-RF is a compact 433MHz RF PIR motion sensor designed to detect movement in indoor spaces and trigger smart home actions through a compatible SONOFF RF Bridge.
• The sensor can detect movement up to 8 meters with a 100° detection angle, making it suitable for corridors, rooms, entrances, offices, storage areas, and indoor security scenes.
• It supports two working modes: Alert Mode, which can trigger every 5 seconds, and Normal Mode, where the next trigger activates after no motion is detected for about 1 minute.
• When connected with SONOFF RF Bridge / RF BridgeR2, it can send app notifications and trigger scenes such as turning on lights, activating alarms, or linking with a camera scene.
• Important: PIR3-RF requires a SONOFF 433MHz RF Bridge to work with the app and smart scenes, and the adjustable motion sensor base is not included by default.
Key Features:
• 433.92MHz RF PIR motion sensor for indoor movement detection.
• Detects movement up to 8 meters in indoor space.
• 100° detection angle for room and corridor monitoring.
• Alert Mode triggers once every 5 seconds when motion is detected.
• Normal Mode reduces repeated triggers by waiting around 1 minute after motion stops.
• Supports smart scene automation through SONOFF RF Bridge.
• Can trigger lights, alarms, notifications, and compatible smart devices.
• Low-energy battery-powered design using CR2450 button cell.
• Compact size for flexible wall, corner, entrance, hallway, and room installation.
• Optional universal joint base allows 360° horizontal and 90° vertical angle adjustment when purchased separately.
• Suitable for security monitoring, lighting automation, and RF smart home scenes.
