The most promising system at the moment looks to be one of these

http://shop.omnisense.com/p/74/drifi-restoration-monitoring-kit-eu-version

(lets me monitor temperature, RH and wood moisture content)

The only thing I don't like about that is that it ties you into a monthly contract for access to their server.

So I've been checking out alternatives. I can find various things that will let me log temp and RH directly, but it seems impossible to find a wood moisture content sensor that I can embed in the wall long-term and then retrieve data by whatever means (it could be cabled or wireless).

It seems surprising, as portable moisture content meters are quite common... I'd have expected to be able to get an embeddable version of the same.

Am I missing something or can anyone suggest anything?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200009#Comment_200009 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200009#Comment_200009 Fri, 11 Apr 2014 18:11:23 +0100 Ed Davies

I need something that will log the readings periodically though, not just when I manually take a reading. I don't mind downloading manually every so often but need a consistent stream of readings over time.]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200031#Comment_200031 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200031#Comment_200031 Sat, 12 Apr 2014 11:07:05 +0100 daserra http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200053#Comment_200053 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200053#Comment_200053 Sat, 12 Apr 2014 17:02:29 +0100 SteamyTea http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200057#Comment_200057 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200057#Comment_200057 Sat, 12 Apr 2014 17:20:17 +0100 CWatters http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200064#Comment_200064 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200064#Comment_200064 Sat, 12 Apr 2014 18:40:09 +0100 PeterW

Table on the last page has the resistance values

Could get an RPi to do a resistance comparator but the wire lengths may play havoc with it

Still find it hard to believe that there's not anything commercially available (aside from that one setup linked to in my OP). Surely moisture content is something other people want to measure over time?]]> http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200153#Comment_200153 http://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=11966&Focus=200153#Comment_200153 Mon, 14 Apr 2014 22:15:59 +0100 Triassic

May be something like this research may help identify how the measurements were carried out and identify the equipment used.]]>
