Projects – Hobbybotics Analog Devices AD595 Thermocouple Breakout V1.0 May 15, 2012June 1, 2012 hobbybotics ProjectsAD595, Arduino Development, Hobbybotics, Hobbyduino, Projects, Reflow, Reflow Oven, Thermocouple I designed a breakout board for the Analog Devices AD595 Cold-Junction Compensated Type-K Thermocouple interface. This breakout board is an alternative to the MAX6675 version I detailed here. Check it out here. AdvertisementShare this:EmailPrintFacebookPinterestTwitterLike this:Like Loading... Related

Hello There. I found your weblog using msn. This is an extremely neatly written article. I’ll make sure to bookmark it and return to learn extra of your useful information. Thanks for the post. I will definitely return.
Great article. I tried out your AD595 library today. I am using it for a thermal run away protection relay project for my reprap. Nearly there, however, I’m switching inputs through two 4051 multiplexers. When I try to switch channels, I can no longer get proper readings. Do you think this could be something to do with the library?
Thanks and sorry for not responding before now. Let me take a look at the library but, first stab would say that the improper readings should not be an issue with the library but, could possibly be with the stated resistance 80 resistance between the selected pin and the common pin. This could affect your sampling time used for the conversion with the AD595. I will take a look at the library as it probably needs some updating for newer version of the Arduino ide.
You’re welcome. I looked at your library and it’s perfect. I can’t see anything in the code that would cause this. I think it’s impedance that’s causing the issue. Back to the drawing board!
