Default Wireless Web-Serving Temperature Probe

Some of you might recall last year about this time I was talking about making a wireless probe for my smoker. Well, I finally did it. The temp probe I've used for a long time to monitor the meats finally died. No choice.

I wanted something to make my life easier. I'm usually fairly busy. And, admittedly, I'm a serious geek (proud of it, too). So, had to involve computers.

I bought an Arduino microcontroller, a type K thermocouple food-grade temperature probe with stainless-sheated leads, a WiFi shield for the Adruino, and a chip to let the microcontroller get info from the thermocouple in a meaningful fashion.

And, I had to write a little software for it because nothing out there existed (or at least, was available).

Cost? About $155. Microcontroller $35. Probe $50. WiFi shield $55. Interface chip $15. My soldering skills came free.

What does it do? It serves up a little web page that tells me the current probe temperature. I love it. From any computer in the house (including my cell phone's web browser), I can check the temperature.

What's next? Multiple probe support (including smoker ambient temperature). Text message (SMS) alerts when target temperature nears or ambient smoker temperature drops too low. Temperature graphs and long-term storage.

Here it is:
