1. A sensor discriminator configured for detecting at least one gaseous substance based on a change in at least one electrical property of a metal organic framework when exposed to the at least one gaseous substance, the sensor discriminator comprising:
a power source;
a discrimination module comprising a comparator;
a sensor simulator comprising at least one simulation component,
wherein the at least one simulation component is configured to simulate the metal organic framework under at least one simulation condition;
a simulation circuitry electrically coupling the sensor simulator to the power source and the discrimination module; and
a discriminator circuitry configured to electrically couple the power source and the discrimination module to the metal organic framework;
wherein the comparator of the discrimination module is configured to perform a comparison of a discrimination pulse to a simulation pulse in respect of at least one electrical property,
wherein the discrimination pulse comprises a first electrical pulse from the power source having passed through the metal organic framework,
wherein the simulation pulse comprises a second electrical pulse from the power source having passed through the at least one simulation component of the sensor simulator,
wherein the discrimination module is configured to generate a discriminator output comprising the comparison of the discrimination pulse to the simulation pulse,
wherein the at least one electrical property depends at least in part on at least one electrical parameter of the metal organic framework,
wherein the at least one electrical parameter of the metal organic framework is augmented by a presence and/or a concentration of the at least one gaseous substance,
wherein the discriminator output is indicative of the presence and/or the concentration of the at least one gaseous substance.
