How to use MAX6675 thermocouple k type with Arduino

Thanks Robojax that's a really good explanation on how to use MAX6657!!

Thank you brother. Use full tutorial.

You are welcome. Here is $200 Arduino course for free Arduino Step by Step Course (over 100 video lectures) Starts here robojax.com/L/?id=338

[@kaushallabba7219]

Thanks for the video. a few questions- how accurate is this? Can i measure the surface temperature of a metal rod using this?

[@robojax]

this is not made for surface but if you put heat transfer compound so there is no gap between the sensor and target surface you should get good result but not very occurate.

[@yinihe7538]

Hi Robojax! Thanks so much for your video. Currently, I am trying to use type K thermocouple with arduino uno. However, One end of my thermocouple are just two bare wires. Does it also works with the MAX6675? Thanks in advance.

[@robojax]

Hi, the one I used that has two wires. the MAX6675 is reading from the two wires and passing it to Arduino which is a micro controller so we can use the value it. if you need the wiring diagram you may watch this video kzbin.info/www/bejne/kJ6biaKolNuMfJY which is part of my Arduino course.

[@yinihe7538]

@@robojax Thanks for providing me the video. So I should be able to use my type K thermocouple with MAX6675 only right? Not need ESP32 bluetooth? Just connecting my two bare wires at the end to the + and - screw in the MAX6675, right? Thanks so much for replying me! Really appreciated!

[@gabrielerossi8398]

Nice tutorial

[@yinihe7538]

Hi Robojax. Do you have videos related on how to do the temperature calibration with MAX6675 or thermistor? My MAX6675 works very well, but I just want to calibrate it! Thanks so much for your help!

[@robojax]

Hi, the module itself does not have (I believe) any calibration feature. But you can compare it against known-good sensor and add or subtract in the value in the code.

[@Thesportynerd16]

put it in boiling water and then in a large bowl of ice water, it will give you two known points roughly 100C apart :)

[@harivignesh7374]

Hi Robojax...! very useful tutorial. I have tried this and it worked. Could you recommend me a suitable temperature sensor module if i want to measure the temperature with 0.1 deg C of resolution. This MAX6675 is providing only 0.25 deg C of resolution and fluctuating of around +/- 1 deg C which is not acceptable for my process temperature measurement. Thanks in advance

[@robojax]

Hi, I have not come across such resolution for this k-type sensor reader. do bing/google search, you might find something.

[@BazaarMonline]

HI; THANKS FOR THE VIDEO I HAVE A QUESTION, I WORK WITH TYPE E , I NEED OTHER MODULE OR THE MAX6675 WORKS WITH ALL THERMOCOUPLE TYPES ?

[@robojax]

Hi, when you write in CAPITAL letters it is screeming 😱 and very hard to read. Now your question: I did an search on Google and got this www.sigmanortec.ro/en/thermocouple-module-type-e-max6675-1024-degrees which shows it works with E Type. So do more reseach or simply test it. Good luck

[@crazydiamonduk]

Curious, if making the lead shorter would this effect the readout? It's probably done on resistance right?

[@robojax]

Yes it will affect the result.

[@crazydiamonduk]

@@robojax That's what I thought. Can the resistance values be manipulated in the Arduino code?

[@robojax]

No. it will will affect the reading. Have a look at the datasheet and see if there is such option.

[@umamahesh-nd7yn]

I have tried many codes which includes your code and also code from Arduino library but still my thermocouple showing 0C and 32F where might be the problem?

[@robojax]

Zero degree means your sensor is either not connected or it is dead. I assume code is not changed .

[@umamahesh-nd7yn]

Robojax bro actually I was provided with F to F jumper wires with my thermocouple but we need to use F to M jumper wires to connect thermocouple to Arduino is it right??

[@haoyuding2012]

Hi Robojax. If I want to use three micro k-type thermocouples to detect temperature at different locations, do I need to order three MAX6675 with one arduino uno? Thanks for your video and help!

[@robojax]

You can use as many as you like on the same Arduino board as long as there are pins. here is the video showing it using two of them with two display kzbin.info/www/bejne/ipyugYh-gqt3n6s

[@miladsalimi9526]

useful, I have two questions1. how can I see the temperature real time in Matlab?2. What is gonna be different if I use another type of thermocouple?

[@robojax]

If you are able to read serial monitor via Matlab, then you can do it. And Matlab can read serial monitor. I have not video on that at the moments.

[@DrTRonik]

İt's so useful tutorial again :), Can we use this sensor for measure " temperature of water" ? Thanks...

[@robojax]

You are welcome.

[@UpSpider]

Yes, you can dip the tip of the sensor also in liquids.

[@DrTRonik]

Thank you, so; I think I can use this sensor for kettle or tea machine...

[@ginanjarbambang7122]

1:48 max 6675 only converter 0.25C, you have solution to read type k without 0.25 resolved, like 50.42C ?

[@herrkronen9694]

Does it matter the pins to make the connection? I mean: Can I use other pins and will it work properly?

[@robojax]

Of course you can use any other and define them in code. I should have mentioned it when explained the code.

[@herrkronen9694]

@@robojax Thanks a Lot ! Excelent Videos !

[@Marknmel1]

Hi @Robojax - do you think it's also workable to share Serial Out and SCLK between multiple 6675's? I would need separate CS lines to enable them. Only 1 could be active at a time. I'm trying to think of a way I could have a few more 6675's on an arduino. (like 8 or more) - Thoughts? Workable?

[@robojax]

Hi, yes you can open multiple serial monitor. see this video kzbin.info/www/bejne/fHm5in-ErrVol9k

[@robojax]

Thanks. The temperature depends on the sensor. you may be able to get it with higher sensing value. Here is my latest video using this as Thermostat for heater and cooler control kzbin.info/www/bejne/mofLaGqtiZJnd9E

[@LuigiZotti]

Hello I have an electric oven that mounts a type K probe inside the chamber, then it must be connected to the controller (plc), do you think I can also connect the same probe to max6675?

[@robojax]

Hello, I am not sure. Just open the oven and connect it to Arduino and see if it work and compare with some known good meter.

[@AQ-ej4vv]

How many sensors maximum can i connect to Arduino Uno? I also have a breadboard, i have 6 sensors, can i put it in one arduino uno?

[@robojax]

Depends how many pins you have on your board

[@DesertJeff]

I put extension wires on the TC and it caused it to not be accurate.

[@robojax]

for the k-type you can't extend it as the length is important due to material type. but for arduino wires, yes you can extend it some distances.

[@almolhamsaleh4779]

Hi, I set up the thermocouple and arduino and was able to get temperature readings, but the change in temperature is incremental. The temperature increases or decreases slowly by 0.25 every half second. I would appreciate it if you can tell me how can I get a quicker reading for a temperature change. or if you can let me know what the issue might be.

[@robojax]

Hi, I have explained it. there is delay inside the loop. play with that if it say dalay(500); then it has delay 500ms. so make it 20 or 100.

[@Weirdomanification]

There will always be a bit of a delay because of the thermal mass of the sensor. Good contact with object of measurement and a sensor with low thermal mass are key for quick readings.

Could you please tell me if I can use it with PLC controller ?

[@robojax]

this is just a sensor. you have to know how to use it. if so you can use it with anything. Arduino is used here to read the values. if you use something else, to read it, it should work. I have no experience with PLC and have no idea with it is. I looked online to buy a kit to make videos but, there is nothing clear about it. so I gave up. I know it is used in the industry but could not find a standard controller or item. on eBay or AliExpress I did not find a single item to be famous. each item i found has sold 10 or 20. so I did not buy it. I want to see if something is sold at least 10,000 time then I know it needed and I would make video. so post the most common name, I will check it and if found to be interesting, I will make series of videos .

Using a meat thermometer, the values update so fast. Please help.
