Temperature read

MAX6675 thermocouple Arduino - SCHEMATIC

Help me by sharing this post

This is a simpel schematic on how to read the data from the MAX6675 driver uisng SPI connection.

Download MAX6675 library:


#include "max6675.h"	//INCLUDE THE LIBRARY

int thermoDO = 9;
int thermoCS = 8;
int thermoCLK = 13;

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("C = "); 
   Serial.println(thermocouple.readCelsius());
   Serial.print("F = ");
   Serial.println(thermocouple.readFahrenheit()); 
   delay(1000);
}
