Microwave Radar Motion Sensor Switch, 220-240V AC, 1200W

This 220V to 240V AC microwave radar sensor switch provides 360-degree motion detection and integrated ambient light sensing for automated lighting control. Utilizing Doppler radar technology, it detects movement across a 2 to 10 metre range while resisting external signal interference. It is well suited for home automation enthusiasts, makers, and facility management applications.

Doppler radar detection

The switch uses a 5.8 Hz continuous-wave radar system to deliver 360-degree omni-directional motion sensing up to a 16m diameter. It detects subtle limb movements to maintain continuous load illumination until occupants leave the area.

Intelligent lighting and delay control

An adjustable ambient light sensor allows configuration between 10 and 2000 lux so connected lamps activate only at chosen light thresholds. The turn-off delay can be tailored from 10 seconds up to 30 minutes after movement ends.

Switching capacity and anti-interference

Equipped with an onboard 10A 250V AC relay, the module switches loads up to 1200W with standby power draw below 0.5W. Built-in signal processing prevents false triggering from mobile, Wi-Fi, and remote control frequencies.

Mounting and positioning guidance

Designed for ceiling mount installation in corridors, stairways, and workshops. When installing in smaller rooms, positioning the unit towards a corner or side avoids the vertical central blind spot.
