Electrical Characterization of Ammonia Carbon-Based Sensors

A sensor response parameters of the ammonia sensors which are prepared by using composite of graphene oxide and poly(4-styrenesulfonic acid-co-maleic acid) sodium salt derived carbon are presented. Using the self-designed interdigitated electrode on the experimental setup, we were able to determine the capacity for gas sensing as a sensor response for low ammonia concentrations (20, 50, and 100 ppm).
