Motion Sensor for SP-AP0511W/L-1, USB Plug-In, Black
Using Passive Infrared (PIR) technology, this sensor automatically turns the fan on/off for
effective odor and moisture control. A field-adjustable delay timer (0–60 min) keeps the fan running as needed to
ensure complete air exchange. When integrated with whole-house ventilation, the fan automatically boosts to high
speed when motion is detected.
