Working Principle: Utilizes FMCW frequency modulated continuous wave to detect human targets within a set space. Combined with radar signal processing and precise human body sensing algorithms, it achieves highly sensitive human presence sensing. It can identify moving and stationary human bodies and calculate auxiliary information such as the distance to the target
High-sensitivity Detection: Using 24GHz millimeter-wave radar sensor technology, it can not only sensitively sense moving people, but also identify static, slightly moving, sitting or lying people that traditional solutions cannot identify
Plug and Play: Supports GPIO and UART output, and can be flexibly applied to different smart scenarios and terminal products
Pin Definition: TX serial port transmission; RX, serial port reception; OUT, sensor output high level; GND, power ground; VCC, power input (5V voltage). The sensor IO level is 3.3V. The default serial port baud rate is 256000, 1 stop bit, and no parity bit
Usage Scenarios: Human body sensing lighting control, automatic control lighting; advertising screen wake-up, automatic opening when people come, automatic sleep when no one is there to save power; life safety protection, automatic detection and alarm in dangerous places to prevent people from entering specific high-risk spaces; intelligent security: detection and identification of people intruding or staying within a specified range
