Micro-Movement Detection can detect small movements such as tilting the head, waving hands, raising hands, swiping a phone, turning pages of books, etc. Presence Detection can detect the human body in stationary states such as standing still, squatting still, sitting still, etc. Motion Detection can detect walking, trotting, fast running, turning in circles, jumping, and other activities. Distance Measurement provides accurate target distance measurement to filter out targets outside the designated area. Illumination Detection can detect ambient light levels. Log Query allows viewing of human presence records and illumination change logs. Parameters such as detection distance are adjustable via the app. Fault Detection enables self-checking of equipment status through the app.Specifications: 1. Transmit Power: 3-5dBm 2.
