Hello.
I want to measure temperature with K type thermocouple and K8055. I’m interested only in temperatures 20-100°C. I tried making OP-Amp amplifier for the TC, but some how it just integrates signal it always is raising…
Anyways i changed gain to my A1 channel, i’ve added 10 Om to R8 and now i have G=(1+R10/R8)=1+(10*10^3/10)~1001. But i have a lot of noise in there, at room temperature the input is spyking from 18-28, any way how to get rid of that? i know probably it’s just too big gain set…
