5.8GHz Microwave Motion Sensor Switch DC 3.3–24V for LED Lights

5.8GHz Microwave Motion Sensor Switch — Hands-Free Lighting Control

Upgrade any LED lighting setup with this compact 5.8GHz microwave radar motion sensor switch. Operating on DC 3.3–24V, it automatically activates connected LED lights — cabinet underlights, mirror lights, aquarium light strips, and more — the moment it detects movement. No more fumbling for switches in the dark.

Made in Mainland China.

Key Features

• Wide Voltage Compatibility: Works with DC 3.3V to 24V power supplies, making it suitable for a broad range of low-voltage LED applications.
• 5.8GHz Radar Technology: Uses microwave inductance sensing at 5.8GHz (±75MHz) for reliable, accurate motion detection — even through non-metallic surfaces like glass, plastic, or ceramic covers.
• Wide Detection Angle: 110°–120° detection cone catches movement across a generous area for whole-room or zone coverage.
• Ultra-Low Standby Power: Draws less than 0.005W in standby mode — virtually zero energy wasted when idle.
• High Load Capacity: Supports up to 50W maximum load (3.3–24VDC), handling most LED strip and cabinet lighting setups.
• Versatile Installation: Mounts on walls or ceilings. Integrates easily with existing lighting or runs independently to convert standard fixtures into automatic sensor lamps.
• Fast Self-Calibration: Completes a 2-second self-test on first power-on, then immediately enters normal sensing operation.
• Robust Operating Range: Functions in temperatures from –20°C to +80°C and humidity up to 93% RH for dependable year-round performance.

Ideal Applications

• Kitchen & bathroom cabinet LED lighting
• Vanity and mirror light strips
• Aquarium & fish tank ambient lighting
• Hallway, closet, and under-shelf LED strips
• DIY automatic sensor lamp conversion

Frequently Asked Questions

Q: What types of lights can this 5.8GHz microwave motion sensor switch control?

A: This motion sensor switch is designed for low-voltage LED applications running on DC 3.3–24V. It works excellently with LED cabinet lights, mirror light strips, aquarium lighting, closet LEDs, and similar strip or panel lights with a maximum load of 50W.

Q: Can the sensor detect motion through glass or cabinet doors?

A: Yes. The 5.8GHz microwave radar technology can sense motion through non-metallic materials such as glass, plastic, and ceramic covers, making it ideal for installation behind or inside cabinet panels and mirror frames.

Q: How is this sensor switch installed — wall or ceiling?

A: The sensor supports both wall and ceiling mounting. Simply orient the sensor face toward the area where movement will be detected. It can be integrated into an existing light fixture or wired independently to convert a standard LED light into a fully automatic motion-activated lamp.

Q: What is the detection range and angle of the microwave motion sensor?

A: The detection angle covers 110°–120°. The effective range varies depending on the individual's movement speed and size, with an optimal detection movement speed of approximately 0.5–1 m/sec. Always mount the sensor front-facing the movement zone for best results.
