This thermocouple is designed with fork terminals. Specially designed for digital thermometer which has k type sensor, suitable for measuring liquid or others high-temperature applications. The MAX6675 performs cold-junction compensation and digitizes the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI™-compatible, read-only format.

K type Thermocouple

Hardware and Software Required

  • MAX6675 Module and K Type Thermocouple
  • Arduino Uno
  • Arduino IDE

Hardware Connections

The K-type thermocouple should be connected to the MAX module and the MAX6675 module should be connected to Uno as follows:

  • Vcc to 5V
  • Gnd to Gnd
  • SCK to digital pin 6
  • CS to digital pin 5
  • SO to digital pin 4

Program for MAX6675 Module and K Type Thermocouple

The user need to download and add the library file which is attached upload the program given below and open the serial monitor to check the output.The user will get output in degree Celsius and Fahrenheit as shown in the image.

#include "max6675.h"
int thermoDO = 4;
int thermoCS = 5;
int thermoCLK = 6;
MAX6675 thermocouple(thermoCLK, thermoCS, thermoDO);
void setup() {
 Serial.println("MAX6675 test");
 // wait for MAX chip to stabilize
void loop() {
 // basic readout test, just print the current temp
   Serial.print(" temperature in C = "); 
  Serial.print("temperature in F = ");
