MAX6675 Module + K Type Thermocouple
This temperature sensor and module makes use of the Maxim MAX6675 K-Thermocouple to digital converter IC to provide a microcontroller compatible digital serial interface (SPI compatible) to provide accurate temperature compensated measurement of the supplied K-Type thermocouple sensor. It has a 12 bit resolution providing temperature readings from 0°C to 1024°C (max temperature of supplied sensor is 450°C) with a resolution of 0.25°C. Screw terminals allow for connection to the thermocouples spade connectors and a 5 pin standard 0.1″ header provides an interface to a microcontroller such as an Arduino development board.
Supplied thermocouple sensor has a diameter of 4.5mm with a 6mm threaded mounting bolt. Total length of sensor including cable and spade connectors is ~100cm.
MAX6675 Module Pinout:
The pin-outs for this module are as follows:
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.
– (or Minus): The K thermocouple minus input.
+ ( or Plus): The K Thermocouple plus input.
