# MAX6675 Thermocouple Library For Arduino boards. The Library implements a set of methods for working with a thermocouple based on the MAX6675 driver. Provides a temperature reading in Celsius, Fahrenheit and Kelvin. Modified version of the [MAX6675-library](https://github.com/adafruit/MAX6675-library). MAX6675 driver measures the output of a K Thermocouple and provides the result to the Arduino via a SPI interface. ## Installation 1. [Download](https://github.com/YuriiSalimov/MAX6675_Thermocouple/releases) the Latest release from gitHub. 2. Unzip and modify the Folder name to "MAX6675_Thermocouple" (Remove the '-version') 3. Paste the modified folder on your Library folder (On your `libraries` folder inside Sketchbooks or Arduino software). 4. Restart the Arduino IDE. ## Circuit Diagram  SO: The module’s serial output. Your Arduino will read this output. CS: Chip Select. Setting low, selects the Module and tells it to supply an output that is synchronize with a clock. SCK: The Serial Clock, an input from your Arduino. VCC: 5V supply GND: Ground. ## Methods ```cpp // Instantiation: /** SCK_PIN - SCK digital port number. CS_PIN - CS digital port number. SO_PIN - SO digital port number. */ MAX6675_Thermocouple thermocouple(SCK_PIN, CS_PIN, SO_PIN); // or /** READINGS_NUMBER - How many readings are taken to determine a mean temperature. The more values, the longer a calibration is performed, but the readings will be more accurate. DELAY_TIME - Delay time between a temperature readings (ms). */ MAX6675_Thermocouple thermocouple( SCK_pin, CS_pin, SO_pin, READINGS_NUMBER, DELAY_TIME ); // Read a temperature in Celsius. double celsius = thermocouple.readCelsius(); // Read a temperature in Kelvin. double Kelvin = thermocouple.readKelvin(); // Read a temperature in Fahrenheit. double fahrenheit = thermocouple.readFahrenheit(); // For older devices. double farenheit = thermocouple.readFarenheit(); // Sets a new readings number. thermocouple.setReadingsNumber(READINGS_NUMBER); // Sets a new delay time. thermocouple.setDelayTime(DELAY_TIME); ``` Created by [Yurii Salimov](mailto:yuriy.alex.salimov@gmail.com).
