In a project, I want to connect 5 type K thermocouples to an Arduino Uno to create a temperature profile. My issue is whether to use the MCP9600 or another amplifier? I'm not entirely sure how to identify the I2C address for each individual thermocouple with the MCP9600. I would appreciate your help!
It appears you have not spent any time with your search engine. Start here: Overview | Adafruit MCP9600 I2C Thermocouple Amplifier | Adafruit Learning System You can connect 8 of them to a UNO without any external multiplexing.
Yes, I tried to do that with one thermocouple (with MCP9600) and it worked. However, I don't understand the circuit with multiple I2C devices, especially when it comes to identifying the resistors for each MCP9600. If you have any sources that explain this, I would be grateful.
Get a copy of the Arduino Cookbook, it will explain it. You might also read the I2C specification, it also explains it. Your search engine is your best friend. Hint pay attention the "A" labels.
