RSSI를 이용한 RF 생물체 감지 센서 구현

we propose a novel idea of using RF energy to detect human or animal movement in rooms or offices. RSSI can be used as an estimate of received signal which will enable us to implement a sensor using microwave transceivers. When live object is moving around in a room where RF transceivers are installed at each corner, RSSI will vary in time from the value without the moving object. In this paper, It was possible to implement low cost intrusion detection sensor that can overcome disadvantages of existing object detection sensors using IR, ultrasound and optical images
