Hi,
I have an ethernet M-duino 21+
Can I directly connect a thermocouple type T? or should I gen an additional shield or amplifier?
Is there any guide/code available in the blog? I couldn't find in.
Thank you

Greetings,
No, you cannot connect a thermocouple directly, as the voltage levels are too low for the analog inputs of the PLC to read it. As you say, an additional shield or amplifier are required. You would need a chip such as the MAX31855.
Thank you for the quick reply!
