Microwave motion sensor GTV CM-3 mini 2000W 220–240V 360°

The GTV CM-3 mini 2000W 220–240V 360° is a microwave motion sensor designed for automatic switching of electrical loads up to 2000 W. Using microwave detection technology, it monitors presence and movement across a full 360-degree coverage area and operates on standard mains voltage. The compact form factor and contactless sensing make it suitable for indoor lighting control and basic automation tasks where reliable presence detection and wide-angle coverage are required.

Advantages

The sensor provides reliable motion detection through microwave technology, which penetrates some non-metallic materials and is less affected by ambient temperature changes than passive infrared sensors. It supports switching of loads up to 2000 W, making it compatible with a wide range of lighting fittings and electrical devices. The full 360° detection angle and compact design enable flexible installation in ceilings or other indoor locations where broad coverage is needed.

Suitable for

• Indoor ceiling lighting in corridors, stairwells and common areas
• Automatic lighting control in utility rooms, storage spaces and garages
• Energy-saving control in offices, meeting rooms and commercial spaces
• Replacement or upgrade of manual switches with presence-based switching

When it may not be suitable

This microwave motion sensor may not be suitable for outdoor installations or locations exposed to direct weather conditions, as it is intended for indoor use. It may also be less appropriate where absolute immunity to interference from other RF devices is required, since microwave sensors can be sensitive to strong radio frequency sources and moving objects behind thin partitions.

Key specifications

• Detection technology: microwave motion detection
• Operating voltage: 220–240 V AC
• Maximum switched load: up to 2000 W
• Detection coverage: 360° angle
• Installation type: recessed or surface mounting options for indoor use

How to use

Connect the sensor to the mains and the load following electrical safety regulations and wiring diagrams provided by a qualified electrician. Position the sensor in a central location to maximize the 360° coverage; avoid aiming it directly at reflective metal surfaces that could cause false triggers. After power-up, test the sensor by moving within the coverage area to confirm correct switching behavior and adjust placement if necessary.

What to consider before purchase

• Confirm the installation location is indoors and protected from moisture and weather exposure
• Ensure the connected load does not exceed the 2000 W switching capacity
• Check compatibility with the building’s mains voltage (220–240 V AC)
• Plan mount position to achieve desired 360° coverage without obstructions

Usage recommendations

For reliable performance, install the sensor at a recommended height and away from strong RF sources or large reflective surfaces. Use it to automate lighting in frequently used indoor areas to improve convenience and reduce energy consumption, and consult a qualified electrician for correct wiring and compliance with local electrical codes.
