The TP-Link Tapo T100 is a compact, battery-powered device (CR2450, up to 2-year life) designed to detect motion and automate smart home routines within the Tapo ecosystem (Tapo Hub required). It offers a wide detection range of up to 7 meters and a 120° field of view, with adjustable sensitivity levels (3m, 5m, 7m) to prevent false triggers. The sensor features a flexible angle for optimal positioning and supports customisable detection intervals (4 to 60 seconds). It enables motion-activated control of other Tapo smart devices like lights and cameras, sends instant alerts via the Tapo app, and can trigger the hub's alarm. Installation is versatile with magnetic or 3M adhesive mounting options, making it ideal for discreet and efficient smart home security and automation.
