The XiuMii Smart Human Presence Motion Sensor utilizes 24G millimeter wave radar technology to detect human presence with high precision, distinguishing between stationary and moving individuals. Unlike traditional infrared sensors, this device can sense subtle movements such as breathing or small gestures, making it suitable for scenarios where constant occupancy detection is required.

The sensor connects via the Tuya Smart Life app, allowing users to monitor presence status, adjust sensitivity, and set automation triggers from a smartphone. The set includes two units, offering extended coverage for larger rooms or multiple zones.

Constructed with a durable ABS shell, the sensor is designed for reliable, long-term operation without frequent maintenance. Its compact form factor enables discreet placement on walls, ceilings, or shelves.

The device operates on a stable 24GHz frequency band, ensuring consistent performance even in environments with temperature fluctuations or drafts that might interfere with passive infrared detectors. While it does not support voice assistants like Alexa, the Tuya integration provides flexible scene creation and scheduling.

The sensor is ideal for home automation systems focused on energy saving, security, and comfort, such as automatically turning off lights when a room is unoccupied or triggering alerts when presence is detected. The product is offered at an exceptionally affordable price point, making advanced presence detection accessible for budget-conscious setups.
