The Carlo Gavazzi BSP-PIR90A-U is a Smart-Dupline indoor passive infrared (PIR) sensor designed for reliable presence and movement detection in building automation applications. Part of the Carlo Gavazzi BSP Series, it combines a wide 90° detection pattern with programmable sensitivity and bus-powered operation for straightforward integration into Smart-Dupline installations.
Designed specifically for indoor wall mounting, the BSP-PIR90A-U can automatically detect people within its monitored area and provide occupancy information to the connected automation system. This enables functions such as lighting, air-conditioning, roller blind and security control to respond automatically according to room occupancy.
The sensor provides a detection range of approximately 0.5–15 m with a 90° operating angle. Its surface-mounted thermoplastic housing, programmable sensitivity and Smart-Dupline bus interface make it suitable for offices, commercial buildings, public spaces and other automated indoor environments.
Passive infrared sensors detect changes in infrared radiation caused by people moving within the monitored area. The Carlo Gavazzi BSP-PIR90A-U communicates detected presence and movement through the Smart-Dupline system, allowing connected building functions to respond automatically without requiring occupants to operate individual controls.
When integrated into a Smart-Dupline installation, occupancy information can be used for automatic lighting, heating, ventilation, air-conditioning, roller blinds and intrusion-related functions. Programmable sensitivity helps installers optimise detection performance for the room and application while the bus-powered architecture simplifies installation and system expansion.
