Arduino Refrigerator Thermostat

[infoseek]

I have a mini fridge that needs a new thermostat. I thought it would be a cool project to build a digital thermostat using my Arduino Uno and LCD. I basically just want to be able to adjust the temp with a pot. I could use some help finding the right temp sensor or any other needed components from your website to complete the project. Thanks!

https://learn.adafruit.com/sous-vide-po ... us-viduino should help. you could also use a TMP36 or MCP9808

Thanks for the info Franklin. The TMP36 looks like the way to go. I was thinking I could mount a project box on top of the fridge for the Uno and LCD display and a relay inside where the original thermostat was to turn the compressor on and off based on the temp settings.

The TMP36 is easy to work with. But for a refrigerator, you should anticipate that you will have some condensation. A waterproof DS18B20 would be my first choice. https://www.adafruit.com/products/381 Although you could make a shroud for the TMP32 with some heat-shrink tubing & epoxy or silicone sealant.

For a water shield I've used this http://www.lowes.com/Paint-Primer/Plast ... B%5D=2z8vj or a product called liquid tape.
