The ads1115 sensor allows you to use your ADS1115 sigma-delta ADC sensors (datasheet, Adafruit_ADS1115) or your ADS1015 sigma-delta ADC sensors (datasheet, Adafruit_ADS1015) with ESPHome. First, setup an ADS1115 Hub for your ADS1115 sensor and then use this sensor platform to create individual sensors that will report the voltage to Home Assistant.
