MAX6675 K-type Thermocouple Module & Sensor

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 reolution providing temperature readings from 0oC to 1024oC (max temperature of supplied sensor is 450oC) with a resolution of 0.25oC. 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 ~50cm.
