Product description: mmWave 24GHz radar fall sensor - Seeedstudio 101990884
The module is equipped with the Infineon mmWave FMCW radar fall sensor, based on a Doppler radar operating in the 24 GHz band , and is an independent short-range sensor (NDS). The device makes it possible to distinguish between busy and unoccupied conditions and to identify human activities in the environment of self-adaptation, especially falls . It uses a UART serial interface for communication, is supplied with a voltage of 5 V, and its outputs work with a voltage of 3.3 V. Compared to the traditional PIR sensor , the fall detection module has greater sensitivity to human actions, such as standing, moving and falling. Contrary to the short response of the PIR sensor, the module constantly detects human movement . Equipped with a standard self-learning algorithm, it can simultaneously detect, protect privacy and can manage various environments. The module has a high-performance dual-array antenna with a fan beam width of 90 ° horizontally and 60 ° vertically, which makes its detection area up to 20 m 2 .
