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 the 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 home, human behave detecting, danger alarm.

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 millimetre-level, it will remain functioning even shelter block. Not like the PIR sensor short responding, the module keeps sensing people continuously which makes it quite useful during the living room, hotel, or even prison.

The module contains a standard self-learning algorithm, it can detect simultaneously, privacy-protectively, and it can manage different environments whether the location is a little noisy or extremely peaceful. Above that, it highly decreases the interference of non-living objects and the detect output is up to 95 % accuracy.

There is a two-array, high-performing antenna built on the module and it has fan-beam pattern beamwidth where the Horizontal is 90° and Vertical is 60° which makes its sensing area as high as 96m2. Additionally, it even can sense micromotion. The module is very adaptable to the environment and it can maintain proper functioning even if the environmental factors are different. The output power is very low which ensures it is harmless to the human body even in prolonged exposure.

The unit supports secondary developments and the improvable factors like small size, digital output, inside algorithm, allow it can be applied in a variety of scenarios applications by universal UART communication interface through a development board like Wio Terminal or the XIAO series.
