Abstract
Systems and techniques are described for motion detection. In various examples, a radar sensor may transmit at least a first frame and a second frame over a first period of time. Difference data representing differences between at least a first signal corresponding to the first frame and a second signal corresponding to the second frame may be determined by the radar sensor. First data may be determined by a passive infrared (PIR) sensor over the first period of time. A first machine learning model may generate, using the difference data and the first data, second data indicating whether motion is detected during the first period of time.
