Description

It's a mini-project to measure temperature. I created it to free up some breadboard space and TC74 isn't very breadboard friendly. I plan to integrate the board into my main project, HouseRemote. The board contains two I2C temperature sensors: a TC74 and a DS1631 because only one temperature sensor is never enough :) I oriented the TC74 sensor in such a way that it can be bolted to a surface to measure the temp on the surface of an object. The DS1631 has considerably higher resolution and accuracy in comparison to the TC74. Github link to files are down below the images.

I've uploaded a photo to demonstrate that the product works (as required by the Square Inch Project.) Temperature readings are in celcius. The lower resolution readings are from the TC74 and the higher resolution (and more accurate) readings are from the DS1631.

Photo for demonstration that it works

Yesterday I've uploaded a photo to demonstrate that the product works (as required by the Square Inch Project.) Temperature readings are in celcius. The lower resolution readings are from the TC74 and the higher resolution (and more accurate) readings are from the DS1631. I used an MSP430G2 launchpad to get the readings from my board.
Wishing everyone a Merry Christmas!
Taking suggestions

The project is mostly finished but I'm most certainly willing to take suggestions. I have been thinking about going from thru-hole to SMD resistors which help reduce board space. I've never worked with SMD resistors although I'd imagine it shouldn't be too difficult.
