Temperature Sensor Thermocouple K-type MAX6675

The Temperature Sensor Thermocouple K-type MAX6675 kit combines a K-type thermocouple with a MAX6675 converter module to measure high temperatures with a microcontroller. The MAX6675 handles cold-junction compensation and turns the thermocouple signal into a 12-bit digital reading over a simple SPI-compatible interface, so it works with Arduino, ESP32 and Raspberry Pi in ovens, smokers, heaters and other high-temperature projects.

• Industrial and lab temperature logging

What's in the Box

• 1 × MAX6675 thermocouple module
• 1 × K-type thermocouple probe

Tip: Connect the thermocouple wires with the correct polarity, as reversed wires make the reading fall when the temperature rises. Read the MAX6675 no more often than about every 250 ms, because each conversion takes around 0.2 s. The probe's own temperature limit may be lower than the chip's range.
