Max6675 Arduino Library Download

I am currently working on a progam utilizing the max6675 library found here. The problem that I am having is that the functions that return temperature (both Celsius and Fahrenheit) do not work without a delay() command after them.

You are doing something wrong. Just load the simple example found here: -library/blob/master/examples/serialthermocouple/serialthermocouple.pde and see that it doesn't have delays after every time it reads the chip.

Herein i confirm that even the simplest code reading max6675 doesn't work for me without proper delay between readings. I found delay(200) is minimum to make max6675 work corectly. Apparently max needs some delay between readings to read TC and stabilize reading.

So I have two MAX6675 breakout boards by different manufacturers, several known good thermocouples, and a few assorted known good arduinos/ATMEGAs. I've tried every hardware combination I can think of on three different libraries, but no matter what the only result I ever get is 0C/32F - even with libraries that use negative return values as an error code!

Hi all.

I encountered a problem on the bluepill board, the max6675 library with a mils delay refuses to work correctly.

For the library itself to work, a delay of 250 or more is required, but since the sketch uses a PID, such delays lead to unstable operation.

When you are using a sensor, or other type of peripheral, it is always handy to use one of the available libraries. Sometimes though there is no library, or the instructions for the peripheral are simple enough to not use a library, or the library gives a lot of overhead.

In an earlier article, I showed how the (excellent) datasheet of the good old BMP180 offers a blueprint on using the sensor without library on an attiny85.

Purely as a learning moment, I will now do the same for an SPI sensor, the MAX6675 temperature sensor on an ESP8266. Yes I know, there is a library available, but consider this just as an exercise in dealing with SPI peripherals.

The MAX6675 datasheet states the following:

In the loop(), we read the temperature and display it on the Serial Monitor. The library provides a method to read the temperature in Celsius and a method to read the temperature in Fahrenheit degrees.

If you need a thermocouple interface that can handle other types of thermocouples, check out our 'Universal' MAX31856 amplifier board which can be configured in the Arduino sketch to interface with just about any kind of thermocouple

New! Now uses the MAX31855K instead of the MAX6675, so it can measure a wider temperature measurement range. Please note! the MAX31855 is not pin compatible or drop-in code compatible with the MAX6675. We do have an Arduino library for both chips but you'll need to adjust any existing MAX6675 designs for the new MAX31855. The MAX6675 has been discontinued by Maxim.

Hi. I think you do not need 15 pins to connect 5 sensors. My count stops at 7 :-).

You need to connect SO pins from all sensors to one arduino pin. Same for SCK.

Only CS pin from each sensor needs to be connected to separate arduino pin.

Hello, I want to measure temperature on LabVIEW using arduino and MAX6675 module. I have browsed past issues and the internet. I could not find any examples that worked successfully. I can measure temperature using the LM35 arduino sensor, but I want to measure via thermocouple using this MAX 6675 module. Can anyone knowledgeable about this issue help? It may be in another thermocouple module that I do not know. If there is, I expect that example from you. If it's happening with rasbery pie, I'd like to learn it too.

Scenario:

I m experimenting the thermocouple amplifier (SN-6675) with Arduino DUE.After i'm included MAX6675 library, Arduino can measured room temperature.However, Temp measured from arduino have 2 issues,

Thank you very much! Tell me, please, can you make a thermocouple with two outputs (with dimensions corresponding to the actual physical dimensions for breadboarding). I am interested in just such a thermocouple as in the first figure on this site -thermometer-max6675-thermocouple-arduino/

The MAX6675 (or newer MAX31856) is an SPI bus device which has Arduino library support, so it can be read via Tasmota, ESPHome or your own firmware. Just needs to be connected to the SPI bus on your microcontroller.

TIP: Set the "#defineThermoOnly" in the example code to uncommented then rebuild the code, thenchoose the menu from the Arduino IDE to plot the temperature:Menu-->Tools-->Serial Plotter. This will plot out the values oftemperature on a graph in real-time. (If you don't see that menu install theIDE from arduino.cc as there are two versions available) .

I am trying to use a switch case function and while function based on the temperature read of the thermocouple. However, when I try to have the arduino read the temp to test the while statement nothing happens. How can I have the arduino read the temp for the while statement?

Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. The MAX31855K does everything for you, and can be easily interfaced with any microcontroller, even one without an analog input. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard or perfboard). Goes great with our 1m K-type thermocouple.

Version 2.0 now includes ferrite beads and filter capacitor onboard for better stability

Hi PeteKnight thank you to answer, yes it is correct they are connected to the same PIN because they use SPI communication where you only need to hace one different PIN (CS) that is set to LOW when the module wants to communicate with the arduino (this peace of code is in the libraries that use SPI).

After you download the library, copy the folder to your arduino directory/library. It is usually in C:\program files (x86)\arduino\library. If your arduino software is running when copying the library. Make sure you restart the software after add the library to let arduino recognized new library. ff782bc1db
