Abstract

A Palladium coated PMMA (Poly Methyl Methacrylate) optical sensor is evaluated to define its response to ambient humidity and temperature. The sensor has an estimated lower detection limit of 15 ppm hydrogen and can detect hydrogen down to 1% in 80% Relative Humidity. Cross sensitivity tests have shown that the sensor shows limited response to 25 ppm H2S and 50 ppm CO.
