- In this very short video, you will learn how you can measure temperature from 0 to 1024 degree Celsius by using K Type Thermocouple sensor with MAX6675 module and Arduino.
You can find the complete details like code and wiring diagram of this Arduino project at circuitmagic.com
Project page - coming soon!
Thank You. Follow your clear instructions one by one. And it works exactly as you show. Great work.
Very good. Can you make a video with a k type thermo couple and an LCD displaying the reading?
Great job! You make this look so easy. I'm going to build it also.
plz send me arduino code for calibration of temperature

@@hamzaqadir9589 I did build the circuit but I used the code from the website. I edited it for 2 thermocouples. However, I did not calibrate it yet. I will calibrate it against an autoclave thermometer, but this will not be universal for all thermocouples. You will need to calibrate the code for your thermocouple by adjusting the maximum and minimum temps during your cycle against a calibrated thermometer. Good luck.
Donna Perygin I am getting temperatures as 0c and 32F everytime can u help me to sort it out I checked my wiring it's similar to video one
@@umamahesh-nd7yn I did this project, but I don't know what happened to the code. If I find it, I will throw in on my GitHub. However, I can't help you with your problem because I haven't done this in a long time. Sorry. Best of luck to you.
can You please send me the code youre site is not working and i need it for a project
How do you calibrate the thermocouple?
Good video. The MAX6675 and MAX31855 thermocouple amplifiers are not compatible with grounded thermocouples. This looks like a grounded thermocouple to me. You will get extremely unreliable results using a grounded thermocouple couple. And be frustrated for weeks. I have been there and done that. Also do everything you can to isolate the arduino from power line noise and if you try to use two on the same arduino be careful of ground loops.
here is a video that explains it very well. th-cam.com/video/qQzh-qeKSzw/w-d-xo.html. The grounded ones will work fine until you touch it to a metal , especially if equipment that has an electric motor attached . I bought a thermocouple digital gauge and two thermocouples . The thermocouples were very simple with just the node showing ,no sheathing. Measured air temperature perfectly. checked it in ice bath , again perfect ,touched it to my heat pump liquid lines (copper tubes) and it was off by about 8 degrees (with or without the motor running). when I hooked both thermocouples up at the same time ,to my heat pump (liquid line and suction line) they were both off by about 25 to 30 degrees. I only use ungrounded thermocouples now. (most cheap thermocouples are grounded.) As far as the Max6675 here are my suggestions. Ungrounded thermocouples only, completely seperate power supply then your arduino or any other electrics in your panel (ie its own transformer adapter or battery) or a very well isolated power supply. Capacitor across the thermocouple leads. Shortest leads as possible.
do a tutorial on how to switch one microcontroller with another. for instance, a function in controlled by connecting a pin to ground on one, the other is a voice module that outputs a 3.3V . how do we do this without using a relay?
how would you wire up more than 1 thermo couple and write all the data to an SD card to read as a text file later?
I already tried this code, but i didnt work. The nominal which was out on the serial monitor was 0 Celcius or 32 Fahrenheit. I cant find the mistake .
Do i have to put the thermocouple to something?
Christine Sonya I am also getting same mistake can u help me
@@umamahesh-nd7yn umh, maybe your device is disconnected or there is a problem with your device. I don't think the code is wrong because it's an easy code. I solved my problem with trying to connect them until 100 times 😅
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?
does the thermocouple shown in this video is GROUNDED or UNGROUNDED junction? Does Max6675 is compatible with GROUNDED junction thermocouple?
I am trying to read from -10 C to 90 C . Is there anything that I would have to modify to your circuit?
Great video.
Question. I'm replacing my ebike motor pcb. My original pcb has 5V GND SP H1 H2 and H3 components that's I'm familiar with and know how to connect.
My replacement pcb has these connections PLUS a "K" (relay?) and "-" beside it.
What is relay used for? Does K mean relay? And, since "K" is not a component on my original pcb does that mean this pcb will not work unless connected to some type relay?
Tried looking online/Google. No luck. Need some help. Hope u can.

Where can i find the component
can we submerge that sensor tip to a boiling water including the silver/coated wire?
Hi. İ did same . But the tempreture value was not net. İt was changing : like this= 65 , 75, 50, 73, celcius. Can you help me . Why is not clear
Can you build an Arduinu controlled ac 220 fan regulator to increases or decreses fan speed according to room temparature please.
[Menacingly] Yessssss..... it's increasing..... 2:43
max degree C this sensor can be read! thanks
my arduino reading is going zero
what can be issue
How to run arduino with matlab/simulink
How many different nodel measure can make with is circuit
I am looking at doing a project with this thermocouple and 4 other thermometers. Can the MAX6675 be used for all 5 thermometers? How do you hookup the MAX6675 to a 3.5mm jack for external replaceable thermometers?
Thanks for your help!
Max6675 is for thermocouples so you should use thermocople connectors or else you measurement will have some error in some temperatures
Where is the code?
can it work for 4 thermocouples ??
What's the name of programming app?????
Do soldering iron goes upto 170 degree
where is link?
Thanks for that video. I would like to know if I can use k-thermocouple and arduino to create a temperature control charger for lead acid battery.
Hey, love the video. I am supposed to make a temperature data logger as a project. I can't figure how to use multiple MAX6675 on an arduino uno board. Can you please help me?
Read my comment in the top sir. I managed to make 3 sensors working.
Short & Sweet.
Can I connect several thermocouples with one arduino
Yeah, I would like to use 16 thermocouples and add an LCD-screen to present the values.
I wonder if it's possible.
and just in C not in C and F
I have seen some guide not use a MAX6675 Module, but they use a more basic temperature sensor.
Is the module necessary for the type K Thermocouple sensor?
Thanks in advance.
It is necessary. Thermocople outputs very small voltage. Also you need board to compensate cold point temperature to get real temperature value. Sorry for finnish ralli english :D
@@jukka5648 thank you very much for the explanation. It was perfect. :)
Hello ; great video. Please i would like to know how to assign a value taken by a thermocouple to a variable (arduino programm) ?Could you help me please
// Sample Arduino MAX6675 Arduino Sketch
#include "max6675.h"
int ktcSO = 8;
int ktcCS = 9;
int ktcCLK = 10;
MAX6675 ktc(ktcCLK, ktcCS, ktcSO);
void setup() {
Serial.begin(9600);
// give the MAX a little time to settle
delay(500);
}
void loop() {
// basic readout test
Serial.print("Deg C = ");
Serial.print(ktc.readCelsius());
Serial.print("\t Deg F = ");
Serial.println(ktc.readFahrenheit());
delay(500);
}
i have lots of fluctuation any help...??
Does this also work with the Arduino Pro Micro ? because i dont have enought space at my projekt ! :)
please can make temperature control with pid
Thanks. Really good video
Great project
Thanks a lot! :)
thankyou verymuch,.
i want to know that what if the output is LED RGB please..
if you want to make it, i would be appreciate that
how about max 31855 can we use it easy like max 6675?
Please show the same project for 3 k type thermocouple
Read my comment in the top sir. I managed to make 3 sensors working.
Thank You very much........ un abrazo..... :)
what is this module (max66..) analog signal output?
What's the name of programming app??
It is very helpful video for me but i have one difficulty is obtain one error and can't measure proper reading. So plz help me to solve error and by using this arduino multiple k type sensor use i know but how? that is unknown for me. So plz help me to make one circuit for multiple sensor.
Read my comment in the top sir. I managed to make 3 sensors working.
Is it possible to do something similar with a T-Thermocouple?
hi, cant you make a video of this + register data on excel or database please :) im noob
What is the range of temp. this sensor can measure.
From 0 to 1024 degree Celsius you can read it in the infobox ;)
@@damaciii6901 what's the name of programming app??
Please try the ntc 100k thermistor for temperature measurement and upload the video with code
Wow
Are you from India?
yes
Make vice control car using motor shiled
