DC 3-5V MAX6675 Module + K Type Thermocouple Temperature Sensor Thermocouple Sensor Set M6 Screw and Jumper Wire F to F 

This MAX6675 Module + K Type Thermocouple Sensor Measure 1024°C Temperature sensor makes use of the Maxim MAX6675 K-Thermocouple to digital converter IC to provide a microcontroller compatible digital serial interface (SPI compatible) for giving an 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 the 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 Ardunio development board.
