5.8GHz Microwave Sensor Module – 2-8m Detection Range

Description

The Knightsbridge OS008 is a 5.8GHz microwave sensor module designed to be mounted inside light fittings, providing 360 motion detection across an adjustable range of 2-8m radius. The module measures 76.7mm x 29.4mm and fits into most pendant, ceiling and wall light back boxes with sufficient depth for the wiring connections and DIP switch configuration panel.

Microwave sensors detect movement by emitting 5.8GHz radio waves and measuring the reflected signal unlike passive infrared (PIR) sensors, they can detect motion through non-metallic materials like glass, thin plastics and lightweight fabric shades. This makes them suitable for concealed installation inside decorative light fittings where a visible PIR lens would compromise the fitting’s appearance. The module includes adjustable lux control to prevent activation in daylight and adjustable time control to set how long the light stays on after the last detected movement
