The ESP8266-12 has a ADC 0-1Volt input.
Because I wanted to measure 3 tanks ie 3 inputs but as you know the ESP only has one built-in ADC and an ADS1115 is a cheap way to get the additional inputs.
I've taken the same approach to monitoring my three battery banks but in that case I used 2 ADS1115s in order to get three differential inputs.
