We investigated the effect of humidity on a set of SnO2 gas sensors. As one might expect, absolute humidity is the only meaningful physical quantity because chemical equilibrium is established by the concentrations of reagents. When absolute humidity is properly compensated for, the gas response follows this dependence because all other parameters keep unchanged.

Abstract
We investigated the effect of humidity on a set of SnO2 gas sensors. As one might expect, absolute humidity is the only meaningful physical quantity because chemical equilibrium is established by the concentrations of reagents. When absolute humidity is properly compensated for, the gas response follows this dependence because all other parameters keep unchanged.File in questo prodotto:
