That way you won't have any worry about the perforated pipe being
a conduit for moisture from in the building.<br>

Yes, Matts, if this sensor were permanently buried in the wall, it
would be useless in about a year. I don’t think this is the
device that we have been waiting for, but rather, like John the
Humidity Baptist, it tells us that the time of our moisture
monitoring savior is coming soon. But if someone wanted to put it
in the wall in a perforated pipe with a removable cap, similar to
a DYI design of 15-20 years ago, then replacing the batteries at
intervals would work.

<div style="word-wrap:break-word" class="">Those
of us who want to monitor the conditions
inside our walls have had a variety of
options, from home-built to industrial, at a
range of prices. However, finding a system
that meets a home builder’s definition of easy
and affordable has been elusive. I just found
a product advertised at Lee Valley Tools,
which shows that the consumer market is
beginning to offer interesting options.
Powered by a CR2032 battery, the device will
log data, and transmit it to an iPhone or
other iOS device for “up to a year”.
Important details are missing, but it looks
interesting. The D2 model costs $159, and
measures temperature accurate to 0.5 degrees
C, and humidity, accurate to 2%, according to
the web page. The device appears to be about
40mm long, 35mm wide, and 13mm thick.
