Hi!
I'm trying to measure the temperature using a Pt100 probe. I used a LM317 to drive 218 µA through the resistance element, and used a TL082 in non-inverting configuration (with a gain of 29) before feeding it into P1_1. I'm averaging 250 ADC samples before converting them to resistance, and then to temperature. The temperature reading is very unstable, as this video shows. Any ideas how I could eliminate this?
Thanks!
