ORNO Microwave Motion Sensor OR-CR-214 — Microwave presence detector OR-CR-214 by ORNO

ORNO Microwave Motion Sensor OR-CR-214 is a presence detector that uses microwave sensing to identify movement and occupancy for automatic switching tasks. The device detects motion by emitting microwaves and measuring reflections, enabling reliable activation of lighting and security circuits. It is intended for indoor installations such as corridors, stairwells and utility rooms where automated response to presence improves convenience and energy efficiency.

Advantages

The ORNO OR-CR-214 provides reliable detection through microwave technology which can sense motion even when indirect reflections occur. Its detection principle offers stable performance in low-light conditions and through certain non-metallic obstructions. The sensor is suitable for integration with lighting and security systems and supports automatic on/off switching to reduce unnecessary energy consumption. Designed for typical indoor environments, it delivers consistent presence sensing for routine automation tasks.

Suitable for

• Automatic lighting control in corridors and staircases
• Presence-triggered switching in utility rooms and storage areas
• Integration with basic security or alarm systems for motion-triggered events

Key specifications

• Detection method: microwave presence sensing (Doppler/reflection-based)
• Application environment: indoor use (corridors, stairwells, rooms)
• Main function: motion/presence detection for automatic switching
• Typical uses: lighting automation and security-triggered switching

How to use

Install the sensor according to mounting instructions at a location with an unobstructed coverage area for the monitored zone. Connect the sensor to the controlled lighting or switching circuit following electrical safety standards and local regulations. Adjust installation height and aiming to achieve the desired coverage; microwave sensors are less affected by ambient light levels but require correct placement to avoid detection dead zones. After wiring and mounting, perform a walk test to confirm detection range and correct operation with the connected load.

Usage recommendations

For reliable operation, place the sensor where movement crosses the coverage area rather than moves directly toward it, avoid mounting near large moving machinery or metal obstructions that can affect microwave reflections, and follow all local wiring codes. Regularly verify operation after installation and before integrating with other automation systems.
