MAX31855K Thermocouple Temperature Sensor Module
MAX31855 K-Type Thermocouple Temperature Sensor Module
This MAX31855 thermocouple module handles amplification and cold-junction compensation for a suitable thermocouple. Its digital interface can be read by a microcontroller without an analogue input, including suitable Arduino boards.
The breakout is described as including the sensor chip, a 3.3V regulator with 10µF bypass capacitors and level-conversion circuitry. A 2-pin terminal block connects the thermocouple, while a pin header connects to a breadboard or perfboard. A compatible 1m K-type thermocouple is available separately and is not included. Verify the supplied board's regulator and level-shifting arrangement before using 5V.
Updated converter This module uses the MAX31855 instead of the MAX6675, supporting a wider encoded temperature range. It is not pin- or software-compatible with the MAX6675, so existing designs need wiring and software changes. Use a library for the correct chip. The MAX6675 should not be assumed discontinued solely because this alternative is available.
Version 2.0 is described as adding onboard ferrites and filter capacitors for improved stability; check the supplied revision.
Technical specifications
| Specification | Value |
| Compatibility | Works with compatible K-type thermocouples |
| Incompatibility | Does not work with thermocouple types other than K-type |
| Temperature range | -200°C to +1350°C output in 0.25°C steps, subject to probe limits |
| Accuracy | K-type thermocouple measurement accuracy is approximately ±2°C to ±6°C, depending on conditions and probe |
| Internal temperature measurement | Yes |
| Supply voltage | Board use at 3.3–5 V requires suitable regulation and level shifting; the bare chip uses 3.0–3.6 V. |
| Interface | SPI data output, requiring 3 digital I/O pins |
| Dimensions (without headers) |
Length: 20 mm Width: 20 mm |
| Included components | MAX31855K chip, 3.3V regulator, 10µF bypass capacitors, level-conversion circuitry, 2-pin terminal block and pin header, according to the board specification |
| Recommended accessory | 1m K-type thermocouple (not included) |
