The motherboard & cat sensor combines the main logic board with our mmWave-powered ActiveShield® detection platform. This all-in-one module manages every function of the machine—from motion sequencing to safety monitoring, while the integrated radar sensor accurately detects cats around the unit. With Sentinel Mode, motion automatically halts when skittish or curious cats approach, providing added peace of mind. Replacing this module restores full intelligence, responsiveness, and safety performance to your S7.
