Multiple Max6675 Arduino, Industrial Temperature Monitor using K type thermocouple & Oled display

[@Tims_Projects]

You don't need to use that many pins on the Arduino. Arduino has hard SPI on pins 11, 12 and 13. (using hard SPI is faster than the soft(x3) SPI you are using here) Arduino pin D12 is MISO (Master In Slave Out), so ALL devices SO (Slave Out) can go to this pin. Arduino pin D13 is SCK (clock), so ALL devices SCK can go to this pin. The CS (Cable Select) from each device go to separate pins of your choice on the Arduino. The Arduino then uses the CS pins to select which device it wants data from. This way it leaves more pins to add more devices. In this case you are not sending any data to the devices, so pin D11, MOSI (Master Out Slave In) is not used. (don't use this pin for CS)

can i have around 8 thermocouples in one arduino ?

[@Tims_Projects]

@@emilianocastelan4845 If you use the Hard SPI, using D12 (MISO) and D13 (SCK). Connect these pins to all devices (Thermocouple Modules) pins SCK to SCK and MISO to MISO. You can daisy chain these and power. Each Cable Select (CS) pin of each device (Thermocouple Module) will need it own pin on the Arduino. Each of the individual pins on the Arduino (CS pins from devices) are activated one at a time. When one is activated, you are reading from that device (Thermocouple Module). So if you have 8 pins free after connecting D11 and D12 (remember pins D0 and D1 are for serial) then yes.

It help me as beginner! I plan to make it as temperature display for my DIY NAS. So I can know the temperature without open the web.

[@santiagolisboa684]

Great Video! I'm working on a coffee roaster to measure Bean and Exhaust temperatures and your video will prove useful. Thanks!

[@fitsumgetaneh7791]

wow an amazing video really love it the way you present is very attractive, clear and brief thanks bro very helpful keep it up!

[@extc_prachetsaul281]

can you make a video on the data should received by the Arduino MEGA was then sent to a Nextion display which displayed all three temperature simultaneously and displayed accurate temperatures.

[@electronic7979]

Very helpful video 👍

[@PhG1961]

Excellent video, well explained and in an entertaining way.

Glad you enjoyed it!

Hi I'm looking for v2 for control ING temp. Very good explanation for monitoring. I could understand it as a beginner. Thanks

[@intruderEvil]

I have 2 Max6675 Sensors. But the Temperature is different. Can i fix die Problem in the Arduino Code? The Differenz ist about 3 Degrees.

[@alessandrolazzari4680]

Thank you very much for your explanation! It was very clear and helpful! I am only left with one doubt I would really appreciate if you can solve it ... Max6675 module uses SPI, however, Arduino has got only one SPI if I am not mistakes... Therefore, how is it possible to connect the other two MAX6675 module? Thank you in advance

[@danyamohammad6437]

always great 👌

[@ElectroniClinic]

Thanks Danya

[@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?

[@zx3215]

Good video, although I personally found those MAX6675 a bit slow... =( Tried measuring temperature of water in industrial cooling system. But it was fun...)

[@ElectroniClinic]

I am planning to use these in plastic injection molding machine.

[@zx3215]

@@ElectroniClinic Good luck on the path)

[@emilianocastelan4845]

can you connect 8 thermocouples along with 8 lcd screens for each one into the same arduino, and would I just copy the part where the thermocouples are defined 8 times ?

[@piyushsharma5205]

Good video!! Can you tell me that whether an arduino mega is capable of running MAX6675 ? and how many maximum of max6675 modules can an arduino UNO support!

[@highperformanceengines3902]

for using many MAX6675/MAX31855 you need to have connected: SCK, SO, and a CS for any MAX6675/MAX31855 you use and make changes in the sketch... for example, if you have 10 digital pins free, you can connect 8 thermocouples (SCK, SO, CS0, CS1, CS2, CS3, CS4, CS5, CS6, CS7).

Is it possible to display hmi instead of o'led?

[@LvtLoshi]

This is excellent thank you, did you ever get around to using this to control a system of heaters/coolers?

[@ElectroniClinic]

I have used it in multiple projects, it's work exceptionally well

[@kellyspoolhall761]

Good video but I was expecting the temperature display to rise much faster with a flame touching the thermocoupler. Is there a better alternative you could recommend?

[@ElectroniClinic]

this is industrial temperature sensor, its a bit slow but works great. you can try ds18b20 temp sensor.

[@kellyspoolhall761]

@@ElectroniClinic Thank you! I will look into it 👍 I will be using it to get water temp feedback from servo-driven valves on the water hydrant on my acreage.

[@kellyspoolhall761]

@Electronic Clinic Could you recommend an alternative that has male threads like the K type?

[@antoniocammarota8061]

Grazie,del bel progetto e di come lo spieghi anche sul sito. Sarei curioso di vedere anche un progetto su come controllare la temperatura, oltre a leggerla con la stessa attrezzatura . Saresti il primo su youtube. Grazie

How can I use MAX6675 with PLC ? I was using Ada8495 earlier, but I lost it and now it's not available in my country, importing it will take 20 days and I have to make my project before 15th January, 2022.

[@engr.omitdebnath]

Can you show the temperature monitoring and controlling system with K-type Thermocouple, STM32 Microcontroller, and Keil Uvision software by using Code? And can you please share that code with us? It will be very helpful for me and many researchers.

what if you want to write these values with a timestamp to a file instead of the display?

[@chickenz4604]

Nice Video Sir!, btw hows the arduino Sir? is it still working ? Iam confused whether i should choose arduino or plc for controlling air temperature in farm and turn on the spray or other stuffs if it is too hot

[@olivervoss3196]

If you take care that the Arduino or STM32 Microcontroller doesn't get wet, too cold or too hot (see corresponding datasheet) or that the air humidity is too high it will run forever ! Also take care that the voltage is alright

[@shinosg-wiz4619]

very nice! Is it possible to make it with 16 sensors? and scrolling on the display or something like that?

[@ElectroniClinic]

ya why not. you can multiplex even more.
