Temperature Sensor with Arduino – K Type Thermocouple Sensor MAX6675 Module

Hi Guys, Last week I made a small Arduino project to measure temperature by using k type thermocouple sensor with Max6675 module. By using this module we can measure temperature 0 to 1024 degree Celsius. In this article you can find the Arduino code and wiring diagram of this project. You can also watch the video tutorial in this page.

Arduino code to measure temperature with MAX6675

// Sample Arduino MAX6675 Arduino Sketch

#include "max6675.h"

int ktcSO = 8;
int ktcCS = 9;
int ktcCLK = 10;

MAX6675 ktc(ktcCLK, ktcCS, ktcSO);

  
void setup() {
  Serial.begin(9600);
  // give the MAX a little time to settle
  delay(500);
}

void loop() {
  // basic readout test
  
   Serial.print("Deg C = "); 
   Serial.print(ktc.readCelsius());
   Serial.print("\t Deg F = ");
   Serial.println(ktc.readFahrenheit());
 
   delay(500);
}
