PMOD – Sleep Mode Enable. A value of 1 in this bit enables the DS2760 to
enter Sleep Mode when the
DQ line goes low for greater than 2 seconds and leave Sleep Mode when the DQ
line goes high. A value
of 0 disables DQ-related transitions into and out of Sleep Mode. This bit is
read-only. The desired
default value should be set in bit 5 of address 31h. The factory default is
0.
So it would be interesting reading the value of PMOD. I assume that DQ is
high when you are accessing the DS2760,
so I'm not sure why it would be in Sleep Mode.
Eric, can you explain further?

Thanks for the parts, by the way. I haven't yet got the humidity board up
