Motion sensor ORNO OR-CR-212 microwave 5.8 GHz 360° detection 1200W white 3–2000 lx

ORNO OR-CR-212 is a microwave motion sensor operating at 5.8 GHz with a 360° detection pattern. Designed for automatic lighting control in indoor or sheltered outdoor spaces, it detects movement through some non-metallic obstacles and can switch loads up to 1200 W. The sensor includes an adjustable light threshold from 3 to 2000 lx, enabling operation only when ambient light is below the desired level. Its compact white housing and omnidirectional coverage make it suitable for corridors, stairwells and entrances where consistent presence detection is required.

Advantages

The sensor offers a wide detection area thanks to its full 360° coverage and high-frequency microwave technology, which provides reliable motion recognition and the ability to sense movement through certain non-metallic materials. Adjustable sensitivity to ambient light (3–2000 lx) allows energy-efficient operation by preventing unnecessary switching during daylight, and the high switching capacity supports a variety of lighting loads up to 1200 W. The white finish integrates with common interior and sheltered exterior installations.

Suitable for

• Corridors and hallways
• Stairwells and landings
• Building entrances and vestibules
• Sheltered outdoor areas such as covered porches
• Utility rooms and storage areas

Key specifications

How to use

Install the sensor according to mounting instructions in a sheltered position or indoors where the coverage area is unobstructed by large metallic objects. Connect the sensor in series with the lighting circuit so that detected motion triggers the light load. Adjust the light threshold to set the ambient luminosity level at which the sensor becomes active; set lower values for night-only activation and higher values for daytime availability. Verify detection range and fine-tune placement or sensitivity as needed to avoid false triggers and to ensure reliable coverage of the intended zone.

Usage recommendations

For optimal performance, mount the sensor at the recommended height and avoid direct exposure to heavy metal barriers or dense foliage that can impede microwave signals. Use the adjustable light threshold to reduce energy consumption by preventing activation under sufficient daylight, and test the installation after adjustments to confirm coverage and switching behaviour.
