ESP8266 has a single ADC pin available. It may be used to read voltage at ADC pin or to read module supply voltage (VCC). > When referring to the ADC pin these terms are used interchangeably: ADC (Analog-to-digital Converter), TOUT, Pin6, A0 or Analog0.

By default Tasmota uses ADC pin to read voltage. The signal comes from an analog [peripheral](peripherals), or sometimes from the device itself (see [Shelly 2.5](Shelly-2.5)). The signal can be interpreted as temperature, lux, button or "generic".
