Hi, I am trying to connect a k type thermocouple to an Arduino uno but I have a problem in choosing the amplifier, if anyone could guide me with this and the connection logic.
I attached a link of the thermocoupe I am using, i would like to ask if MAX6675 or MAX31855 works with this K thermocouple?
The datasheets will indicate compatibility if this is true.
Either will work, as will any thermocouple amplifier for type K thermocouples. However, most breakout boards don't have the matching connector.
I moved your topic to an appropriate forum category @juli200017.
In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
You can get a matching connector and use thermocouple wire to connect to the board. You need to be keep the cold junction at the terminals where the board probably compensates for.
I got most of the answers from Gooogle Ai when I put "MAX6675 vs MAX31855" in Google.
