This radar assembles multiple functions in one device which are customizable with your own definitions.
It can detect human presence and absence, the motion and the direction of motion, object speed, and detected distance. Meanwhile, it provides the open custom function by offering adjustable underlying parameters for you to adjust detected range, sensing sensitivity, trigger threshold, valid time for states changing, and installation environment.
There is also an underlying open function provided and the parameters from it are the statics noise of the environment, the detection range of presence, motion noise of the environment, the detection range of object moving, and the detection speed of an object moving. That is, you can utilize its performance to build your own object movement detection radars, to meet the different needs in various scenarios.
What's FMCW's advantages?
Based on the principle of millimeter wave radar and FMCW ranging technology, the radar only needs to calculate the high-frequency continuous waves emitted to and received from the objects, without any privacy risks. Designed with a low power output, the radar maintains health-friendly working status when it is observed. Thanks to its high immunity against interferences, the output data is less vulnerable to environmental influences like temperature, humidity, noise, airflow, dust, light, etc.
