Thank goodness the problem was a bad sensor. I ran a test also with no
problems:
p...@amd64$ for x in 1 2 3 4 5 6 7 8 9 ; do /opt/owfs/bin/owread
/uncached/26.3D3A15000000/humidity ; sleep 1 ; done
27.505 27.505 27.8532 27.505 27.505 27.8532
27.505 27.505 27.505
As for which sensor to use, I've been using the AAG sensors (in the old
stainless steel packaging) for several years with no problems. Are you
certain it's the HIH3600 sensor inside?
