Is It True That ESP32 Has Noisy Analog Inputs, and Can I Mitigate This with Resistors and Capacitors
Interesting, I hadn't heard about noise on the inputs. Seems like I've programmed this sort of thing (though probably not ESP ADCs) to take a number of readings and average them together for data points.
Per a previous post https://discord.com/channels/1130679493799977062/1230604933699600495/1301970745580195871 I've been thinking about using an ESP32-based datalogger and its analog inputs for measuring CR2032 performance over time, so hopefully the ADCs are not TOO bad. The linked product there might be something to consider for inspiration on your design. I haven't tried it, but the device seems to have some very good features, especially for its ~$30 price tag.
