    Yeah, I know. They are a pain in the butt. But they pay the bills to keep my server running. Just a fact of life, I am afraid.

    Want to get rid of them? Simple. Just become a Contributor level member or above and they will be gone. -> Please click HERE."

    Is that too much for me to ask of you to keep this site running? Well, sorry about that. I too wish I could get everything for free. But alas.....

    Google Adsense ad revenue for December, 2025 was just $30 over the cost of the lease for the server running this site. So, in effect, the money providing the incentive for me to continue running this site is coming SOLELY from the paid memberships and sponsorships here. Which honestly ain't much....

Here are the results of a little project I started in 2005. It's an on-line, programmable temperature controller that I'm working on:

Here is a link to more info and the current temperature in my reptile room:

Interesting.

Why not just integrate an on-board NIC instead of using a serial interface?

Or a USB interface. I don't even have a computer with a serial connection anymore. But yes, interesting.
 
The PCB board only comes with a serial connection, but one of these would probably work... haven't tried it myself.

Serial to USB Cable

I suppose the software (which I am writing) would have to be modified to read/write to the USB port as well, but that should not be a problem.

I thought about the USB angle - but you still need a PC to handle the communications. I'd prefer to have a self-contained unit that didn't require additional hardware.

Ah ok, so you mean a wireless NIC instead of an ethernet one. I totally agree that would be ideal. No need to go hook up to the unit to program and it gives it the internet access at the same time.

That could also be accomplished if a USB port was included with just a wireless USB adapter. That could cut down on production costs and give customers a choice between hardwired or wireless. With USB adapters being so cheap now it would cost a customer to upgrade to wireless if they wished.

Now the programming the unit to work wirelessly is another story. I don't have the knowledge on how easy or difficult that would be.

I'd settle for either wired or wireless.

Either way its definitely feasible, you could easily embed a web server in the unit itself which would eliminate the need for connecting the device to the PC.

There are quite a few companies that manufacture similar set-ups for temperature and humidity monitoring, but I'm unaware of any thermostats that offer this type of functionality.
