Easy to use Household Temperature Monitor?
Jim Carroll asks: "I awoke this morning to a gas furnace that conked out. The house was 60F. We had to turn the switch off and on to get it working again. Fair enough -- but I'm worried about it going off when I'm travelling and having the pipes freeze. I'm looking for an inexpensive, simple to use temperature monitor/sensor that would plug into a USB port, that would then log household temperature to a server, so that I can view it through my broadband connection while travelling. Sure, there are all kinds of complex X10 solutions; there seems to be a few kits out there; and some high end industrial applications, but these all involve spending a few hundred dollars. I want simple, straightforward, cheap -- plug it in, and it dumps the temp every few minutes to a file. But there doesn't seem to be anything that is simple, $10-20, that is consumer oriented? And if not, why aren't companies yet making this type of device?"
Get an alarm system from ADT. They have all kinds of monitoring as 'value added' services. Things like CO, basement water sensors, temp sensors, fire sensors, smoke sensors, and intruder alert sensors. I'm sure you could build an open source LINUX solution with USB, serial, parallel, and apt-get.
Or, have a neighbor pop over and check once a day.
