Abstract
A chemical sensor module includes first to n-th (n is a natural number of 2 or greater) graphene sensors; and an exposure mechanism exposing the first to n-th graphene sensors to first to n-th aqueous solutions containing a sample substance and having different concentrations of phosphate ion, magnesium ion, or sulfate ion. The chemical sensor module identifies the sample substance from the difference in electrical characteristics of the first to n-th graphene sensors.
