Arduino-Compatible MAX6675 K-type Thermocouple Sensor Module

The MAX6675 performs cold-junction compensation and digitises the signal from a type-K thermocouple. The data is output in a 12-bit resolution, SPI-compatible, read-only format.
 
This converter resolves temperatures to 0.25°C, allows readings as high as +1024°C, and exhibits thermocouple accuracy of 8 LSBs for temperatures ranging from 0°C to +700°C.

Wiring:
GND =  Connect to system ground.  This ground needs to be in common with the MCU.
VCC =   Connect to 3.0 – 5.5V.  Typically connected to MCU operating power.
SCK =   Serial Clock Input.  Connect to any digital pin on MCU.
CS =      Chip Select.  Connect to any digital pin on MCU.
SO  =     Serial Data Output.  Connect to any digital pin on MCU.
