Earthquakes are one of the most devastating and frightening natural disasters that can be experienced. After such occurrences, it may be vital to identify objects or (living) beings within buildings that have collapsed. In this context the usage of scanning techniques employing Wi-Fi allow an innovative approach to facilitate referred identification. By using wireless technology, this work presents a proposal for the detection and identification of object contours or silhouettes through walls. This goal was achieved by reading the radio signal strength (RSS) variations with an array of affordable IoT (Internet of Things) Wi-Fi antennas.
