WENTRONIC Goobay Mini motion sensor 79604 — battery-powered passive infrared detector

The WENTRONIC Goobay Mini motion sensor 79604 is a compact, battery-powered passive infrared (PIR) detector designed for indoor presence detection. The sensor detects human motion and can switch connected lighting or alarm systems, providing basic automation for corridors, closets, bathrooms and entryways. Its small form factor and low power consumption make it suitable for locations where a discreet, maintenance-light motion sensor is required.

Advantages

The device combines a compact housing with passive infrared detection to deliver reliable movement sensing while consuming little power. Battery operation allows flexible installation without wiring; the simple mounting mechanism supports quick placement on walls or ceilings. The sensor provides straightforward on/off switching for lighting or alarm inputs and is aimed at energy-saving automation in small indoor areas.

Suitable for

• Corridors and hallways where automatic lighting is desired
• Small rooms such as closets, pantries or bathrooms
• Entryways and vestibules for presence-activated lights
• Basic alarm or alert systems requiring motion-triggered input

When it may not be suitable

This PIR detector is intended for basic indoor presence detection and is not designed for outdoor use or harsh environments. It does not provide advanced features such as adjustable detection zones, integrated ambient light measurement, or multi-sensor networking. For installations needing precise coverage mapping, professional-grade detection or tamper-resistant housings, a more advanced sensor should be considered.

Key specifications

• Detection type: passive infrared (PIR) for human motion
• Power source: battery operation for cordless installation
• Application environment: indoor use
• Typical mounting: wall or ceiling mounting in small spaces
• Primary function: presence/motion-triggered switching for lighting or alarm inputs

How to use

Install the Goobay Mini motion sensor on a wall or ceiling at a recommended height for the target area, following the included mounting instructions. Insert the specified batteries and ensure correct orientation of the sensor lens toward the area to be monitored. Pair or connect the sensor output to the lighting or alarm control input according to the receiving device's setup. Test the detection area by walking through the monitored zone and adjust placement if necessary to avoid detection blind spots.

What to consider before purchase

• Intended installation location: indoor, away from direct drafts, heat sources and open windows
• Battery maintenance: periodic battery replacement required depending on usage
• Detection limitations: basic PIR detection without advanced configuration options
• Mounting surface and height to ensure adequate coverage of the monitored zone

Usage recommendations

Place the sensor at a height and angle that cover typical walking paths; avoid pointing it directly at heating vents or large windows. For energy-saving lighting control, combine with fixtures or controls that support low-duty switching and verify compatibility with the connected control unit before final installation.
