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.

 

Specification:


Package included :
1 x MAX6675 Module

 

How to interface MAX6675 Module and K Type Thermocouple with Arduino Uno?

 
K type Thermocouple

Hardware and Software Required

Hardware Connections

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

Program for MAX6675 Module and K Type Thermocouple

The user need to download and add the library file which is attached here:File:MAX6675-library-master.zip.Now 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.begin(9600);
 Serial.println(''MAX6675 test'');
 // wait for MAX chip to stabilize
 delay(500);
}
void loop() {
 // basic readout test, just print the current temp
   Serial.print('' temperature in C = ''); 
  Serial.println(thermocouple.readCelsius());
  Serial.print(''temperature in F = '');
  Serial.println(thermocouple.readFahrenheit());
   delay(1000);
}
