Introduction: Arduino and Thermocouple K MAX6675
Connecting the thermocouple K MAX6675 to an Arduino Mega.
For this example I used a cheap arduino mega 2560 from SainSmart.
The thermocouple K MAX6675 is a convert that allows temperature reading from 0ºC to 1024ºC. You can learn more about it by read the datasheet here.
Step 1: Material
1 - Arduino
2 - ThermoCouple K MAX6675
3 - USB Cable
Step 2: Wiring the Material
So now we connect the thermocouple to the pin 45 to 53 (in the arduino the pins goes in pairs)
Step 3: Coding Like a Pro...
First of all I need to find a Library who help us to communicate with the sensor. After browsing the web for a couple of hours and testing the libraries, I enjoyed that one, ThermoCoupleK from LadyAda who I believe don't mind if we use it.
After looking at some examples I ended with this code (that is close to the one I found).
Step 4: Conclusion
As you can see it's quite easy to create a K-type temperature reader. Now it's up to you to found an application to this instructable.
That's all folks
Look a potato made it!
We have a be nice policy.
