I have always been interested in electronics, still remember designing and making PCB back in school. The availability of good reasonably priced electronics is amazing, also a lot of rubbish out there too
Did a bit of research into the Raspberry Pi last night and thermocouple measuring. Came across this product that is designed for a type K thermocouple, not the best for cone 10, but, after searching the forum if I can desolder the type K chip and purchase the right thermocouple type it 'should' work.
Is it best to go for type S, or type N or type R. I am a little lost there. New chip seems to be around $5
No idea how this is going to work out, only studied basic programming on linux but there seem to be enough tutorials out there to copy and past my way to something that could work.
The MAX31855 performs cold-junction compensation and digitizes the signal from a K-, J-, N-, T-, S-, R-, or E-type thermocouple. The data is output in a signed 14-bit, SPI-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1800°C and as low as -270°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from -200°C to +700°C for K-type thermocouples. For full range accuracies and other thermocouple types, see the Thermal Characteristics specifications in the full data sheet.
