I bought the one made by Adafruit. Here are the results of using it.
Here are the results I got.
The vertical axis is mV and the horizontal axis is the number of measurements.
There is noise. There seems to be a problem with the ADC reading, wiring, or power supply.
That's right. It has a noise of roughly +-50µV.
In order to do this, I also need to add a column for the measurement time to the RAW data, right?
Is it useful to record time using millis()? A sample file is attached below.
With the library I'm using, the SPS of ADS1115 does not seem to be unadjustable.
In another library, for example, ADS1115_WE, various settings can be made.
