MAX6675 Temperature Sensor Kit with K-Type Thermocouple

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. This MAX6675 breakout board does everything for you, and can be easily interfaced with Arduino, micro:bit, Raspberry Pi and any other microcontroller via 12-bit resolution SPI bus.

A thermocouple works by taking two wires made of dissimilar metals, connecting them at the two ends, and making a temperature gradient between one end and the other (a 'hot' end and a 'cold' one). Once this is achieved, a voltage potential is formed and current flows. This thermocouple breakout takes a standard Type-K thermocouple in one end, digitizes the temperature measured and sends that data out the other end via a SPI interface, thereby interpreting the data and translating it for you to read!

The MAX6675 Thermocouple Breakout requires a power source from 3.0V to 5V and only draws 1.5mA maximum. The kit comes with a K-Type Thermocouple covered with a metal braid. The thermocouple is rated up to 600°C, so it can be used in high temperature measurements such as heaters and ovens. There's a small piece of heat shrink on the end to keep the metal braid from fraying. If you're using at >250°C temperatures, simply remove it with a small blade.
