The Philips Hue Motion Sensor 3-pack enables automated control of Philips Hue smart lighting by detecting movement, turning lights on when motion is sensed and off after a preset period of inactivity. This battery-powered sensor operates on two AAA batteries, providing wireless placement flexibility without requiring a power outlet. It connects to the Philips Hue ecosystem via the Hue bridge and Hue app, allowing customization of light scenes for different times, such as daytime and nighttime settings. The sensor is designed for indoor use in areas like bathrooms, basements, or garages, and can be placed on shelves, tables, or mounted on walls using the included screw. Compatibility is limited to Philips Hue lighting products, ensuring seamless integration with existing setups. Note that battery life depends on usage and will require replacement over time. The pack includes three sensors for broader coverage in multiple locations.
