The TP-Link Tapo T100 is a smart motion sensor designed to automate your home by detecting movement within a 120° viewing angle. It can sense activity from up to 7 meters away, and you can fine-tune its responsiveness using three adjustable sensitivity levels to avoid false triggers. A small LED indicator lets you know the device's status at a glance. This compact white sensor measures 42.3 x 42.3 x 34 mm and can be placed on a flat surface or attached to a wall using the included double-sided adhesive tape. It runs on a single CR2032 battery, which provides power for up to 2 years, making it a low-maintenance addition to your security setup. To function, the device requires a Tapo Hub and operates best in environments between 0 °C and 40 °C.
