The ever-growing oil and gas industry has led to the high demand for technologies which accurately sense defects in underground pipelines. Creating a cost-efficient, real-time monitoring system is very challenging. Radio frequency identification (RFID) based sensors are a hot topic for use with buried pipelines because they do not require batteries and are very affordable. Most RFID systems do not function optimally in the presence of magnetic materials especially carbon steel pipes that are prevalent in the Oil and Gas industry. This thesis proposes a passive RFID sensor platform which can be attached to buried pipes. Using magnetic induction-based communication, the designed platform intends to function correctly no matter the soil composition. Simulated, and experimental results are presented and compared. Different communication methods are detailed, and a new sequential-based method is introduced which shows great immunity to the interference effects of metal on conventional RFID systems.
