The SDT-OSDL/BT-CM-AC is a dual-tech Bluetooth sensor, which merge Passive Infrared (PIR) and Ultrasonic technologies for highly accurate occupancy detection. It also include daylight harvesting and 0-10V dimming to further reduce energy consumption in commercial indoor spaces. This combination enhances performance in complex spaces and provides a cost-effective solution for energy savings that meets building energy codes. By leveraging Bluetooth® NLC, the first wireless standard for professional lighting applications which ensures unmatched scalability and reliability, the wireless lighting control system can be seamlessly expanded with Bluetooth® NLC-certified products and/or compatible Bluetooth® switches as needed.
