I would like to ask you for advice. I need to make a alarm that will by trigger when some object will have more than 80℃. I used for a test kettle with boiling water and on:
- from 25 meters camera mesure 57℃,
- from 15 meters camera mesure 70℃
- from 7 meters camera mesure 88℃
How can I reduce difrenc betwen measurements and growing distance?
Also I wona ask how I can check how far can be the obcect with temperature I wants to mesure and how big it must be?
I will be grateful for your help.
