P1.1.20 Effect of humidity on ammonia sensing by molecular materials

T. Sizun, M. Bouvet & J.-M. Suisse
In gas sensor domain, cross-sensitivity between humidity and ammonia is not well studied in literature. Humidity can induce variation on gas sensor responses and also affect the devices lifespan. The aim of the present work is to clarify the effect of humidity on the response of a resistor used for NH3 monitoring in air quality applications. This survey performs experiments under different relative humidity levels to verify the effect of humidity on the conductivity of...
