Tested and works on esp8266/esp32
Analog-to-digital converter or higher-precision ADC.
The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. See ADS1015 ADS1115 for more information about the hardware.

Get a single-ended ADC reading from the given
Read the conversion results, measuring the difference between the P (AIN0) and N (AIN1) input. Returns a signed value since the difference can be either positive or negative.
Read the conversion results, measuring the difference between the P (AIN2) and N (AIN3) input. Returns a signed value since the difference can be either positive or negative.
Set up the comparator to operate in basic mode, causing the ALERT/RDY
pin to assert (go from high to low) when the ADC value exceeds the
Return value: none.
In order to clear the comparator, we need to read the conversion results. This function reads the last conversion results without changing the config value.
Set the gain and input voltage range; one of the following:
