MAX6675 K-type Thermocouple Module
The MAX6675 module provides a digital interface for a compatible K-type thermocouple probe. Together, the module and a suitable probe can measure temperatures for monitoring projects. Select the module or probe variant required; the probe's own temperature rating limits the usable range.
The MAX6675 is a cold-junction-compensated K-type thermocouple digitiser originally from Maxim, now Analog Devices. It converts the measured temperature to digital data available through a serial SPI-compatible interface. Its resolution is 0.25°C; resolution is not the same as measurement accuracy.
To integrate this component into a project, see the guide from The Curious Scientist
MAX6675 - Thermocouple module Example
Technical specifications

| Accuracy | Converter thermocouple error is up to ±2°C from 0–700°C under datasheet conditions; probe and installation add further error. |
| Resolution | 12-bit (0,25°C) |
| Conversion time | ~170 ms |
| Thermocouple type | Type-K |
| Probe length | Approx. 45cm (18 inches) |
| Probe material |
Positive conductor: Chromel (nickel-chromium alloy, red terminal) Negative conductor: Alumel (nickel-aluminium alloy, blue terminal) |
| Insulation (probe) | Fibreglass |
| Connection (probe) | M6 thread (can be screwed into a suitable mounting point such as a heatsink) |
What is included?
- 1x MAX6675 K-Type Thermocouple Module
Or
- 1x K-type thermocouple probe
Note: Use only within the temperature limits of the selected probe, insulation and mounting arrangement. The converter's range does not establish the probe's safe operating temperature.
Warranty and shipping
We do our best to test all electronics before sending them to you.
This helps us maintain quality and avoid unnecessary trouble during development. Faults can occur, but we encounter them very rarely. If there is a problem with the equipment you ordered, you can always contact us, and we will gladly help you resolve it.
We dispatch from Aarhus to Denmark and Sweden. Shipping options and prices are shown at checkout. Delivery time depends on availability, destination and shipping method; contact us before ordering if you need an item by a specific date.
