One of the primary drawbacks of using electronic sensors for continuous corrosion monitoring in remote locations is the need to provide power and communications at the test location. The present work explores the use of a low-power wireless sensor network to overcome these challenges. Such a network allows sensors to be powered by locally installed energy harvesting elements (i.e., thermoelectric, solar). The communication protocol of the wireless sensor network permits each node to communicate with every other node and store (back-up) data for the entire network. The result is a robust and easily deployable network of sensors that spans large distances. The current effort focuses on the development of conductivity probes that are compatible with industry-standard internal corrosion monitoring infrastructure (i.e., access fittings, coupon holders) and amenable to integration into a low-power wireless sensor network.
