Datasheet

If you are using the MAX31855 v1.0 in a noisy environment, you may need to add a 0.01uF capacitor across the

thermocouple leads.

The MAX31855 does not support grounded thermocouples - if the sensor touches ground the chip will return an error

Arduino Library

If you have an older MAX6675 breakout, download the MAX6675 Arduino library code by going to the github page

and clicking Download Source. Then uncompress the folder and rename it MAX6675 and install it into the library folder

according to our handy tutorial.

If you have the newer MAX31855 breakout, download the MAX31855 Arduino library code by going to the github page

and clicking Download Source. Then uncompress the folder and rename it Adafruit_MAX31855 and install it into the

library folder according to our handy tutorial.

Restart the Arduino IDE and open up the File->Examples->MAX6675/Adafruit_MAX31855->serialthermocouple sketch

and upload it to your Arduino. Once uploaded, open up the serial port monitor to display the current temperatures in

both Celsius and Fahrenheit
