Open box Human Presence Sensor Sonoff SenseGuard Presence Core 24G (SNZB-06P24) – 24 GHz mmWave Radar Technology, Continuous Lux Sensor, 7 Detection Zones, Zigbee 3.0, USB-C Power Supply

Description

Sonoff SenseGuard Presence Core 24G (SNZB-06P24) represents a major evolution of the SONOFF presence sensor range. The move to a new-generation processor and a 24 GHz mmWave radar module delivers surgical precision in identifying human presence in the room, putting an end to those annoying situations where the lights switch off automatically while you are reading, working at the computer or watching TV.

The SNZB-06P24 model brings essential improvements over previous generations: a built-in ambient light sensor in lux with continuous measurement, the ability to divide the monitored space into 7 independent detection zones and a smart algorithm for learning and filtering out interference. The 360° adjustable magnetic mount and Zigbee 3.0 connectivity allow fast, ultra-stable integration into your Smart Home ecosystem.

Key Features & Technical Advantages

• 24 GHz mmWave Radar Technology (Micro-Motion Detection): It identifies imperceptible movements of the human body (breathing, typing, slight head movements). The sensor knows you are in the room even if you are sitting completely still.

• 7 Configurable Detection Zones: The coverage range of up to 4 metres and 110° can be divided into 7 individual distance zones. You can enable or disable specific zones to avoid detection in front of open doors or in secondary walkways.

• Automatic Calibration and Interference Filtering (Spatial Learning): The built-in calibration function lets the sensor learn its surroundings and ignore repetitive sources of non-human movement (ceiling fans, indoor air conditioning units, curtains moved by the wind).

• Built-in Ambient Light Sensor (Real Lux Reporting): It continuously measures the light level in lux (not just a binary night/day state). This allows smart automations to be created based on the exact brightness threshold in the room.

• Bluetooth Setup & Zigbee 3.0 Protocol: Zigbee 3.0 connectivity ensures instant response times on the local network. In addition, the built-in Bluetooth module allows advanced detection parameters to be configured directly via the eWeLink app, even when the sensor is paired with third-party gateways.

• Continuous Power via USB Type-C: To keep the 24 GHz mmWave radar permanently active without interruption, the sensor is powered directly at 5V DC via the USB-C port (cable included in the package).

Ways to Use It and Scenarios

1. Smart Lighting in the Office / Living Room: Set the LED strip and light fittings to switch on when you enter the room, keeping them on continuously while you work at your desk. The light switches off only 30 seconds after you actually leave the room.

2. Lux-Conditional Automation (Energy Saving): Program the lighting to switch on when presence is detected only if the ambient light level drops below the 50 Lux threshold (e.g. at dusk or on cloudy days).

3. Walkway Zone Filtering (Custom Zones): Configure the sensor to monitor presence only in Zone 1-3 (the sofa/TV area) and to ignore Zone 6-7 (the hallway next to the living room door), eliminating accidental switch-ons.

Package Contents

• 1 × Sonoff SenseGuard 24G presence sensor (SNZB-06P24)

• 1 × Adjustable magnetic mounting base

• 1 × USB Type-C power cable

• 1 × 3M adhesive pad + Cable management clip set + Fixing screws

Practical use cases

• Placed on a desk or shelf with its magnetic base, it keeps the light on while you work motionless at the computer and switches it off only after you leave the room.
• Mounted on the living room wall, it detects presence on the sofa even when you are watching TV without moving, and the areas near the door can be excluded from detection.
• Used together with the integrated light sensor, it switches the lighting on when entering the room only if the ambient light level drops below the threshold set in lux.
