Akamatis Human Presence & Light Sensor Litos v3, mmWave Smart Motion Sensor, 2.4 GHz Wi-Fi, Adjustable Sensitivity, Requires Home Assistant (White, 1 Pack)

LITOS v3 — Compact mmWave Presence Sensor with LD2401 and Seeed C3
LITOS v3 offers improved Wi-Fi range and stability thanks to an external antenna. It features the proven HLK-LD2401 24GHz millimeter-wave radar, capable of detecting both motion and stationary objects at distances up to 20 ft (6 m) indoors. This makes LITOS v3 ideal for smart lighting, occupancy monitoring, energy-saving automations, and security applications.
At its core is the compact Seeed XIAO ESP32-C3, delivering reliable Wi-Fi performance. The combination of the LD2401 radar and ESP32-C3 provides accurate presence detection in a very compact enclosure.
【Home Assistant Required】
Works exclusively with Home Assistant, the open-source platform for local smart home control and automation. Requires an existing Home Assistant installation. Basic familiarity is recommended.
【Integrated Ambient Light Sensor】
LITOS v3 includes an integrated VEML7700 ambient light sensor, since many automations depend on both presence and lighting conditions. Its sensitivity closely matches the human eye, allowing accurate ambient light measurements — ideal for automations such as turning lights on only when someone is present and the room is dark.
【Refined Light-Permeable Front Design】
The front panel is made from high-quality 3D-printing filament that allows ambient light to pass through naturally. This helps ensure accurate light readings while adding a clean and modern appearance.
【Ready-to-Use ESPHome Firmware】
LITOS v3 comes pre-flashed with ESPHome for straightforward setup. No manual flashing or additional configuration is required.
