50 type K with i2c bus (or similar)

I am looking for a solution to connect ~50 type K to an Arduino Nano.
I have found the MCP9600 which supports the i2c bus, but is only able to set 8 different IDs.

Is there another solution?

Worst case, I would use an Arduino MEGA and MAX6675 (or the new version of it), but that would mean 52 cables leaving the MEGA. A bus system would be much prettier :slight_smile:

Seven of these might do it.

What sensor distances are we talking about here ?

Draw a sensor run example schematic.

I2C mux:

You have to think what you will do with all the data you will end up with too.
What is the project - thermocouples are not ideal for measuring low temperatures
