Effect of Humidity on Ammonia Gas Sensitivity of Intrinsically Conducting Composite Films

Abstract

Abstract Summary: The effect of humidity on the ammonia gas (NH 3 ) detection of conducting composite films was investigated. The first results showed that the presence of humidity, acting as interference gas, modifies the behaviour of sensors in the presence of ammonia. However, the behaviour study at atmosphere without ammonia of our materials in controlled temperature and humidity allowed distinguishing atmospheric effect from NH 3 pollution.
