Hi all,
I have a Traeger meat probe that has a 1000Ω RTD in it that I want to hook up to an AtMega328P to show on an LCD screen. I see many circuits out there, like the MAX31865 and others from Adafruit, but I got to thinking, couldn't I just use the RTD as one half of a voltage divider and just use a precise power supply to make sure the power is always 5.00V ± 0.1V?
Thanks and stay safe,
Joe
