5.8G Radar Sensor Switch — lights that notice you.

A battery-powered 5.8 GHz radar sensor paired with a 433 MHz mains receiver: lights come on when someone walks in and go off 30 seconds after they leave. No internet, no app, no wiring at the sensor — power the receiver and it just works.

EZ2C 5.8G Radar Sensor Switch — radar sensor puck and KL1L wireless receiver with specifications

Built for

1
Corridors, lobbies & stairwells

Auto-ON when someone walks in, auto-OFF 30 seconds after the space empties — no switches touched, no lights left burning.

2
Basements & restrooms

Radar reads motion, not body heat — reliable in hot plant rooms and steamy restrooms where PIR sensors lose sensitivity.

3
Retrofit without wiring

The coin-battery sensor sticks anywhere — even concealed behind gypsum, wood or glass, since radar penetrates non-metal materials. Only the receiver wires in at the light.
