Reliable temperature monitoring
I am using this to monitor the temperature of my 3D printer hotend. It handles the heat well and provides real-time data without lag. Highly recommended for hobbyists.

Great for prototyping
We used several of these for a university lab project. They performed consistently across all units. The range is sufficient for most general-purpose industrial sensing tasks we encountered.

Excellent build quality
The PCB looks professional with clean soldering. The cold junction compensation seems accurate as the readings stabilize quickly after power-on. Will buy more for my next batch of sensors.

Works as described
As a beginner, I found the pinout labeling clear. It took me a few tries to get the code right, but that was my error, not the hardware. Once running, it measures temperature precisely.

Good accuracy, easy to wire
Setup was straightforward using existing libraries. The screw terminals make connecting the thermocouple wires very secure. I deducted one star because the datasheet link on the package was broken, but online resources filled the gap.

Perfect for Arduino Projects
This module works flawlessly with my Arduino Uno. The SPI communication is stable, and the readings are consistent when compared to my calibrated digital thermometer. Great value for the price.
Q: Does this come with the thermocouple probe included?
A: No, this listing is for the MAX6675/MAX31855 breakout board only. The K-Type thermocouple probe must be purchased separately.
Q: Can I connect multiple of these modules to one microcontroller?
A: Yes, you can connect multiple modules by using separate Chip Select (CS) pins for each module while sharing the Clock (CLK) and Data (DO) lines.
Q: Is this module compatible with 3.3V logic microcontrollers like ESP32?
A: Yes, the module operates within a voltage range of 3.0V to 5.5V, making it fully compatible with 3.3V systems like the ESP32 and Raspberry Pi.
Q: What is the response time for temperature changes?
A: The conversion time for the MAX6675 chip is approximately 220ms. The actual response time to temperature changes depends largely on the mass and type of the thermocouple probe used.
Q: What library do you recommend for reading data with Arduino?
A: The standard 'max6675' library available in the Arduino Library Manager works perfectly. There are also forks available that support both MAX6675 and MAX31855 chips.
