Exactly as described
Arrived quickly and works exactly as the datasheet says. The cold junction compensation seems accurate even when the board gets warm. Very satisfied with this purchase.

Good value, accurate enough
Great little sensor for hobbyist projects. It handles high heat well. I deducted one star because the included pins were slightly bent, but that was an easy fix.

Solid performance
Works great for temperatures up to 800C in my kiln project. Just make sure you have a good 3.3V or 5V supply. The documentation online is plentiful which helps.
Q: Does it measure negative temperatures?
A: The MAX6675 chip is designed specifically for measuring temperatures from 0°C to +1024°C. It does not support negative temperature readings.
Q: Does this module come with the thermocouple probe included?
A: No, this listing is for the MAX6675 breakout board only. The K-Type thermocouple probe must be purchased separately.
Q: Can I use this with a 3.3V logic microcontroller like ESP32?
A: Yes, the MAX6675 operates between 3.0V and 5.5V, making it fully compatible with 3.3V systems like the ESP32 and Raspberry Pi.
Q: What is the maximum wire length for the thermocouple probe?
A: While there is no strict limit, we recommend keeping extension wires under 10 meters to maintain signal integrity and accuracy. Use shielded K-type extension wire for best results.
Q: Is there an Arduino library available for this sensor?
A: Yes, there are several open-source libraries available in the Arduino Library Manager. Search for 'MAX6675' to find popular options like the one by Adafruit or Rockmelt.
