LD2410 Sensor ============= .. seo:: :description: Instructions for setting up LD2410 sensors. :image: ld2410.jpg Component/Hub ------------- .. _ld2410-component: The ``ld2410`` sensor platform allows you to use HI-LINK LD2410 motion and presence sensor (`datasheet and user manual `__) with ESPHome.
