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.

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