I spend a lot of time away from home. It gets pretty cold in these parts so I should probably monitor my house temperature when I'm away.

I don't have a phone line so the classic telephone solutions that would call you in low temps won't work for me. What I'd like is something that can connect to a PC and email me if the temp drops below a certain threshold. Does this exist?

Check National Instruments for the correct module plus LabView.

Yes LabVIEW will do it, but it would not be cheap at all, you would be talking thousands of dollars. Then you would have to learn to program in LabVIEW to make it work. Or I could do it for a small fee :)


Try looking at http://www.lacrossetechnology.com/
They have somewhat cheap weather station and software that can be hooked to the internet.

$2-3 for RS-232 <> I2C bridge, $1 for I2C temp sensor (LM75 or so), and then you write a teeny script...

It cost like $90 at costco, has USB serial interface, can read all the data over the USB, and using this custom software create graphics with text overlays showing any of the data, the software also will allows you to define an ftp upload location and interval for the updates.

It would work perfect for this I believe. It has wireless stations and they can be wired too for more frequent sensor updates.

For ~$35 I would get an Arduino (or similar) and a handful of thermistors. Then you could monitor all main rooms in your house. But the $16 solution above seems sufficient.

Are you looking to have the ability to change the temp while you're at it, or just monitor? "Oh no, the temp in my home is 33 degrees. A couple more degrees and my pipes will freeze, but at least I know!" :p

Microchip FTW:

I use these in an embedded programming class I teach, it has direct web interface via TCP/IP stack built in. The chip itself can do up to 13 analog inputs simultaneously.

Just monitor. I am going to hide some spare keys at work so if there's a problem I'll call a coworker to go check it out. :)

The $15 solution posted here I think will work perfectly! Thanks guys.

Here's a simpler and cheaper option that would be good for beginners.

Arduino - $30

Ethernet Shield - $45
Use with this Ethernet library

Temperature Sensor - $2

That's all you need, except for a programming cable. Using the prebuilt Arduino libraries, you can achieve what you want with a few lines of code.

This is a good option for a beginner. A person with experience could do the project for cheaper than this. Either way, you certainly don't need a fancy $100+ board.

Btw, the Arduino stuff would be good for the future as well. You can set it up to monitor and control practically everything in your aquarium.

I personally used an AVR microcontroller (the same chip Arduino is built around) for my aquarium controller, but Arduino is really popular among beginner electronic hobbyists and its certainly powerful enough for a reef controller.

An example of an Arduino reef controller:

Hi,

Welcome to AnandTech Forums. I locked the thread because the previous reply was over four years ago.

Our members refer to such posts as "necro" posts, and some of them tend to post replies ranging from sarcastic to hostile, including possible accusations of spamming, whether warranted or not.

You are welcome to continue posting on our forums. Thanks for understanding. We hope you enjoy yourself on our forums. :)
