IWRL6432: Selection of millimeter-wave radar for Smart curtains

Part Number: IWRL6432
Other Parts Discussed in Thread: IWRL6844

Tool/software:

The millimeter-wave radar applied to smart curtains needs to recognize different signals through gestures or arm movements to control the opening, closing, and pausing of the curtains.  The recognition distance should be 3 meters or more, and it should be low power consumption and small package.  1) Could you please help check if the IWRL6432 is suitable and if there are any more suitable recommendations?



2)Can millimeter-wave radar detect the presence of a human body at low power consumption and then give a signal?  If supported, what is the power consumption?  What is the detection distance?

    It might be difficult to achieve hand gesture recognition at 3m or more however if larger arm motions as used it may be more reliable. We have a gesture recognition example for IWRL6432 which detects gestures at 2m (user guide). IWRL6844 might be more suitable for this because of the improved angular resolution that comes from the additional tx/rx, however we don't currently have any gesture recognition example for that device.

    Yes this can be done. Here is an example of what is possible with IWRL6432. These results are taken from the video doorbell example. However it is important to note that the average power consumption and detection range both depend on the configuration parameters that the radar uses.
