Detection of ammonia can be done using gas sensors. Examples of different application areas of ammonia gas sensing are; environmental monitoring, medical diagnostics, chemical laboratories and detection of ammonia in portable water and wastewater (Timmer et al., 2005). High concentrations of ammonia are easy to detect while for very low concentrations we require different gas sensors operating at different sensing principles. Ammonia gas sensors operate at different temperatures each having a specific
supercapacitors. Conducting polymer based super capacitors using proton and lithium ion conducting solid electrolytes have received considerable attention recently and several supercapacitor modules have been fabricated using polythiophine, polypyrrole, polyaniline and their related composites to achieve energy storage of about 200F/g. Generally the voltage of a super capacitor is dictated by the available potential window prior to the commencement of any irreversible anodic and cathodic faradaic processes
