MAX6675 Module + K-Type Thermocouple: precise temperature measurement up to 800 °C

If you regularly work on electronics or DIY projects where temperature matters, a reliable sensor is essential. The MAX6675 Module with K-type thermocouple is exactly that: compact, affordable, and impressively accurate. With a 0–800 °C range and 0.25 °C resolution, it’s a smart choice for both hobbyists and professionals.

The price stands out immediately. For just €1.11 including VAT you can order this module on AliExpress. Crucially, there are no extra charges.

What makes the MAX6675 module special?

This module is built around a chip from MAXIM Integrated, the U.S. company known for high-quality components. The core provides cold-junction compensation and linearity correction, so your readings stay trustworthy even when ambient temperature fluctuates.

Communication uses a simple SPI interface, ideal for Arduino, Raspberry Pi, and other microcontrollers. Wiring is minimal: three lines and you’re already reading accurate temperature data.

The included K-type thermocouple is metal and comfortably handles up to 800 °C. That makes it suitable for ovens and melting projects as well as experiments in chemistry and electronics.

Use cases and user experiences

Reviews show high satisfaction. One buyer reported testing up to 250 °C and that it “worked like a charm.” Others highlight the solid build quality and that the module “works perfectly” for hobby projects.

Given the low price, it’s smart to order a few spares. AliExpress frequently offers bundle perks like €2 off orders from €15. See the offers here: MAX6675 on AliExpress.

Why not buy from dropshippers?

You’ll find similar modules on unknown sites, often for several times the price of the same item. AliExpress typically offers free returns, whereas dropshippers often charge high fees or refuse returns. Don’t overpay. AliExpress combines low prices, clear terms, and thousands of happy customers.
