MAX6675 K-type thermocouple temperature sensor(เฉพาะโมดูล)

MAX6675 thermocouple module temperature sensor(เฉพาะโมดูล) Parameters : Operating voltage: 3. 0 ~ 5. 5V Internal integrated cold junction compensation circuit; With a simple three serial interface; Temperature signal can be converted into 12-bit digital Temperature resolution of: 0. 25 Degree; Cold junction compensation range: - 20 ~ + 80 Degree, Embedded thermocouple break detection circuitry. Using SPI 3 wire communication K-type temperature probe Type K temperature range 0-800 degrees These pins function as follows: SO: The modules 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. (or Minus): The K thermocouple minus input. + ( or Plus): The K Thermocouple plus input. https://github.com/adafruit/MAX6675-library Code: // 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); }
