5.8GHz Microwave Ceiling Motion Sensor – 360° Detection, Day & Night
Experience the convenience of lighting that turns on before you even reach for the switch. This 5.8GHz microwave ceiling motion sensor automates your lighting seamlessly. Unlike standard PIR sensors, this microwave technology detects movement through materials like plastic, glass, and fabric, ensuring no blind spots.
Note: This sensor is designed exclusively for ceiling mounting in indoor or covered outdoor areas. The maximum load capacity is 100W. We recommend installation by a qualified electrician.
Why choose this model? (Key Advantages):
- 5.8GHz Microwave Technology — Immune to air currents, small pets, or temperature fluctuations; it reacts only to human presence.
- Detection Through Materials — Can be mounted behind plastic or glass lampshades without losing performance.
- 360° Coverage up to 8 Metres — Perfect for hallways, stairwells, car parks, warehouses, and ceilings up to 6 metres high.
- 4-Stage Range Adjustment — Customise the detection zone to 10%, 50%, 75%, or 100% to prevent unwanted triggers from adjacent areas.
- Flexible Timer Settings — Choose from 4 intervals: 6 seconds for quick transitions, up to 15 minutes for offices or storage rooms.
- 4-Level Lux Control — Set the sensor to trigger only in darkness (2 lux) or 24/7 (2000 lux) for maximum energy efficiency.
- Compatible with LED, CFL, and Incandescent — Works with any bulb type, provided the total load does not exceed 100W.
Performance and Technical Details
The 5.8GHz frequency band is specifically dedicated to motion detection, offering high immunity to environmental electromagnetic interference. Unlike PIR sensors that require a direct line of sight, microwave waves penetrate common materials, allowing the sensor to be integrated discreetly within a light fixture.
The adjustable 4-stage range eliminates false triggers from nearby corridors or outdoor traffic. With a configurable ambient light threshold between 2 and 2000 lux, you can ensure the light only activates when you actually need it, saving energy during daylight hours.

Programming and Usage Instructions
- Set Detection Range — Select one of the 4 levels (10%, 50%, 75%, 100%) based on the size of the area.
- Adjust Timer — Choose your preferred duration (6s, 45s, 5min, 15min) using the time dial or switch.
- Configure Lux Threshold — Set to 2 lux for night-only operation or 2000 lux for 24/7 activation.
- Ceiling Mount — Fix the sensor at the desired height (max 6m), centred in the traffic area for optimal 360° coverage.
- Test — Once connected to the 220V supply, walk into the detection zone to ensure the light activates instantly and switches off after the set interval.

Frequently Asked Questions
What is the difference between a microwave sensor and a PIR sensor?
PIR sensors detect body heat variations and require a direct line of sight. Microwave sensors emit 5.8GHz radio waves that pass through plastic, glass, and fabric, providing more precise detection without blind spots or false alarms from draughts or small pets.
Can it be mounted inside a glass or plastic light fixture?
Yes. Microwave technology works efficiently even when mounted behind a plastic or glass lampshade with no significant loss in performance.
Is it compatible with LED bulbs?
Yes, it is compatible with LED, CFL, and incandescent bulbs. The only requirement is that the total load does not exceed 100W.
Can I use the sensor during the day?
Yes. Set the lux threshold to 2000 lux, and the sensor will activate the light regardless of ambient light. At 2 lux, it will only react in darkness or very low light.
What is the optimal mounting height?
Up to 6 metres. For standard 2.5–3m ceilings, the 360° coverage is at its peak. At greater heights, set the detection range to 100% to compensate.
Is it suitable for outdoor use?
Yes, but only in covered outdoor areas such as porches, patios, or under eaves. It is not designed for direct exposure to rain or excessive moisture.
