Further studies are reported on a novel room temperature tin oxide-pla
tinum sensor for carbon monoxide (CO). The expected porous nature has
been confirmed by scanning electron microscope pictures of these senso
rs. Pore sizes were 0.1-10 mu m. Recovery studies confirm that high re
sistance sensors recover more quickly. During the recovery a second fi
re can be detected and there are no signs of self-poisoning by CO. Pre
liminary results are presented for temperature and humidity cycling. (
