The mmWave Human stationary Presence Radar Sensor Module is a self-contained module near distance sensor based on Infineon mmWave FMCW industrial radar operating at 24GHz. The unit is built with the enhanced Doppler radar signal processing mechanism and standard algorithm which enables distinguishing between occupied and unoccupied conditions and identifying human activities in a self-adaption environment. It is an ideal solution for high-accurate, self-regulation, privacy-protected, secure biotic radar systems in individual applications, such as smart homes, human behavior detection, and danger alerts.

Compared to the traditional PIR sensor, the Human stationary Presence Module has more sensitivity to human activities like standing, moving, and falling. And because the transmitting wave is millimeter-level, it will remain functioning even shelter block. Not like the PIR sensor's short response, the module keeps sensing people continuously which makes it quite useful in the living room, hotel, or even prison.
