Ambient room temperature sensor (digital USB thermometer) suggestions?

[marvinmartian]

I'm looking for a digital thermometer that I can plug into my PC (preferrably USB) so that I can do things like:

if (room_temperature > 90F)
     set_miner_speeds (low)

else if (room_temperature > 85F)
     set_miner_speeds (med)

else
     set_miner_speeds (high)

I do this pretty much manually now, but I see no reason why it couldn't be automated.

EDIT:  One with an API that works under Linux too.

Mhm,

How about Using the GPU Temp Sensors for that ? Or maybe, the Southbridge Sensors.

I'm currently working on one right now...arduino based, hardware remote reset/power for multiple rigs added...I have the GUI done in "processing" all I have to do is add the thermistor code (resetter is done)...I will release all of it in the forums in the next week or so...just have to get it all done.  Based off an Arduino Mega and epcos thermistors...should cost less than $100 to build the entire thing ($70 of that being the arduino but you can use that for other things if no longer needed for bitcoin).  Once its working I hope others can expand it to do everything you are asking it to.  Shouldn't be an issue since all the necessary info will be there.  It will have 2 thermistors...one for ambient (close to computers) one for the room.

If I didn't have a million things going on at once it would already be on the forum.

You can find the setting you needed from Trixx.
Using the custom fan control.

would a thermometer like this one do the trick. one of the reviews mentions that it's compatible with UTAC

--EDIT -- Looks like deslok beat me too it.

The software that comes with it is garbage and only runs in win 32, but there is open source code to read them.

The hardware inside tends to vary a lot, with different serial interface chips in different lots. What ever is cheapest at the time I guess.

And you might have to pad the numbers it produces to get a decent calibration.

On the other hand... It's cheap.

Quick search on ebay for "usb thermometer" turns up lots of cheap choices.

Now just need to see which ones are generic enough to work with any software.

Edit: Seems the first one for $1.60 +4.75 shpg puts the temp value into a log file every second. So you could easily script something to read the last line and use that value.
