Introduction: Dual PIC Thermometer

Picture of Dual PIC Thermometer

The geek inside me has always wanted a fridge that shows the inside temperature for both the freezer and the fridge compartments. However, when we recently replaced our very old fridge we ended up getting a new one without the built in thermometer. So I decided that one of my next projects would have to rectify this problem.

For further information on how I made this, including all details you need to build your own, please see my blog entry @

What is the temperature range of your thermometer? I would like to use it to monitor my Smoker and/or Grill What is my nice comment MMMMM. I guess it would be 'I like your idea. It looks like a good plan to help monitor my outdoor grill and smoker.I would like it to be able to range from -32 to 550. (my dream but, it would be nice.)' Thanks for your insight.

It's range is -55°C to +125°C (-67°F to +257°F) according to the manufacturer.
If you need to measure higher temperatures, like 550, as you said, I would recommend using a thermocouple. I have experimented with them as well and am going to use one in an upcoming project of mine. Stay tuned :) The combo I use is a type k thermocouple and MAX6675 Cold-Junction-Compensated K-Thermocouple-to-Digital Converter (0°C to +1024°C)
