MAX31855 Thermocouple Amplifier, Faulty Description

Post by stabbing hobo »

I've bought the MAX31855 and noticed I was getting wrong and invalid readings while I had my arduino connected to the ground via charger or laptop with charger plugged in. I'm measuring boiler temperature in my espresso machine and the thermocouple is grounded through the boiler.

Now, in the store page it says MAX31855 "Works with any K type thermocouple", while it doesn't support grounded thermocouples.

Thanks for the heads-up. I'll ask the web team to correct that. If the MAX31855 is not suitable for your project, please contact [email protected] to arrange for a refund.
