SMARTFY Four-in-One KNX Sensor | Motion, Illuminance, Temperature & Humidity Detection

SMARTFY Four-in-One Sensor | Intelligent KNX Environmental Sensor

Product Overview

The SMARTFY Four-in-One Sensor is an advanced KNX-based environmental sensing device that integrates infrared motion detection, illuminance sensing, temperature monitoring, and humidity measurement into a single compact unit. Designed for smart homes, hotels, offices, and commercial buildings, it enables intelligent, energy-efficient automation of lighting, HVAC systems, and scene control.

With powerful internal logic functions, flexible channel outputs, and master–slave motion control capability, this sensor allows precise automation based on occupancy and environmental conditions. Its discreet ceiling-mounted design ensures seamless integration into modern interiors while delivering reliable and accurate sensing performance.

Key Functional Features

1. Illuminance Loop Output: Continuous illuminance value output for precise lighting control.

2. Dual Illumination Control Channels: Supports 1-bit, 4-bit, and 1-byte data output for flexible KNX control logic.

3. Infrared Motion Trigger Control: Enables occupancy-based automation of lighting and systems.

4. Motion & Brightness Logic: Combines motion detection with ambient light levels for intelligent decision-making.

5. Infrared Motion Master–Slave Function: Supports coordinated multi-sensor installations in large spaces.

6. Channel Enable/Disable Control: Independently enable or prohibit outputs for illumination, motion, temperature, and humidity via KNX objects.

7. Multi-Condition Lighting Control: Uses combined data from motion, illuminance, temperature, and humidity to control lights more intelligently.

8. True Four-in-One Detection: Infrared motion, illuminance, temperature, and humidity sensing in one device.
