ABSTRACT
The RF sensors can also be used as an Occupancy sensors. Such sensors have been used in a variety of daily life applications to manage air conditioning, home lighting, heating and determining the presence of human beings in residential or commercial avenues. These sensors overcomes the limitations like higher false alarm rate, cost and failure in detection of the stationary subject, etc. of conventional infrared or ultrasonic counterparts. Hence, it has drawn much attention of researchers and practitioners these days due to its wide range of applications in the modern era of smart homes and avenues. Further, the utility of the multiband RF sensor for the prediction of direction angle of arrival (DoA) is also discussed herein. This feature of the RF sensor makes it a versatile device for the law enforcement and military applications.
