1. A system for detection of microbiologically induced corrosion, comprising:
at least one cathodic protection device configured to generate a signal corresponding to the presence of corrosion proximate a structure;
at least one odor sensor configured to generate a signal corresponding to emission of an odor caused by the presence of microorganisms proximate the structure; and
at least one diode-transistor logic digital circuit connected with the at least one cathodic protection device and the at least one odor sensor,
wherein the at least one diode-transistor logic digital circuit is configured to perform a logic gating function based on a pre-logic set according to a decision matrix,
wherein each diode-transistor logic digital circuit is configured to process the signals from the at least one cathodic protection device and the at least one odor sensor and, in response to a first signal indicating the presence of corrosion, generate a first notification corresponding to the presence of corrosion proximate the structure,
in response to a second signal indicating the presence of the odor, generate a second notification corresponding to the presence of the odor proximate the structure, and
in response to both the first signal and the second signal, generate a third notification corresponding to presence of microbiologically induced corrosion proximate the structure.
