Ledgebit Zigbee Human Presence Detector – Ceiling Mount | Zigbee Bridge-Hub Required

Precision Human Detection: 5.8GHz mmWave radar accurately senses both dynamic motion and static presence, outperforming PIR by detecting subtle signs like respiration or slight shifts, while ignoring non-human factors like curtains or fans—ideal for reliable occupancy monitoring in quiet scenarios.App Customization and Control: Via Tuya Smart Life, remotely adjust sensitivity, range, and timing parameters for tailored performance; differentiate between macro (full motion) and micro (static) events to create nuanced automations, such as gradual light dimming upon vacancy.Light Sensing Integration: Embedded illuminance sensor (0-3000 Lux) enables smart rules, like activating night lights only in dim conditions or deactivating appliances in bright rooms, promoting energy efficiency and user comfort.Ecosystem and Voice Compatibility: Zigbee 3.0 ensures stable connectivity in hub-based networks; works with Alexa for voice commands (e.g., “Check hallway occupancy”), Home Assistant for advanced scripting, and Tuya for multi-device scenes—link to locks, sirens, or HVAC for comprehensive home intelligence.Alerts and Security: Instant app notifications on presence detection; supports integrated alarms for deterrence; pairs with Tuya cameras for event-triggered recording, enhancing safety without constant surveillance.Mesh Networking Advantages: Zigbee protocol allows signal extension through other devices, improving coverage in large or multi-story homes; lower interference than Wi-Fi in crowded networks, with energy-efficient operation despite AC power.Simple Setup and Robust Build: Ceiling installation with AC wiring; durable ABS construction withstands indoor environments; operates reliably across temperature/humidity ranges, with privacy emphasis as radar avoids visual/audio capture.Versatility and Edge Cases: Suited for elderly monitoring (detect prolonged stillness), pet-friendly homes (ignores animal movements), or energy optimization; consider hub dependency for setup—test in metallic-heavy rooms where radar penetration might reduce; app OTA updates ensure future-proofing.
