Abstract: This study presents a low frequency RFID (LF-RFID) sensing system integrated with Internet of Things (IoTs) to detect and characterize corrosion. The LF-RFID sensing sys-tem comprises of a tag and reader inductively linked with each other. Tag interacts with corroded metal through eddy currents and measure changes in corroded surface conductivity and per-meability. Sensitivity and impedance of LF-RFID sensor varies with distance between tag to reader; which is adjusted to find the optimum working range. The static and transient features of LF-RFID sensor signal is used to characterize corrosion at low com-putational rate. The size of commercial low frequency tags is very small compared to structures in practice. So, IoTs is used to make a wireless sensor network of proposed sensing system. Re-sults showed an enhancement in sensitivity to corrosion charac-terization at optimum distance between tag and reader. Using IoTs, several sensors are cascaded to make WSN and enable monitoring a wide structural area.
