I’ve got a Raspberry PI 4, a breakout board and the MCP9600 board (oh and a K type thermocouple). I’ve got it all connected, installed the relevant python libraries and got the test code running. However…
The value I’m getting back on the cold junction is “mostly” around 29c (in a room that’s only 20c) with the quite frequent 16.0625c and the very occasional 21c. It’s all over the place. At the same time that the cold junction is telling me 16.0625 the delta is giving me -0.0625. When the cold junction is returning me 29c the delta is mostly around -4c.
The values just seem a bit whacky?!?!?! Any ideas when might be going on, I’ve had a peek at the library but to be honest I can’t see how these values are being generated. Any ideas anyone?
