Tips: Why does a microwave presence sensor stay stable in varied environments?

A microwave presence sensor analyzes Doppler shifts caused by micro-movements—such as slight body motion or airflow disturbance—allowing it to penetrate non-metal materials and remain unaffected by ambient temperature, dust, or light conditions. Its low-power radar pulses continuously assess reflected signals, filtering noise through frequency discrimination to maintain consistent sensitivity across different room layouts. This ensures reliable activation in hallways, stairwells, and entry areas. With its adjustable range and Lux settings, this model provides precise control for smart-lighting scenarios while delivering stable performance in diverse installations.
