@ -63,7 +63,7 @@ ESP32 Attenuation
On the ESP32 the voltage measured with the ADC caps out at ~1.1V by default as the sensing range (attenuation of the ADC) is set to ``0db`` by default.
Measuring higher voltages requires setting ``attenuation`` to one of the following values: ``0db``, ``2.5db``, ``6db``, ``11db``.
There's more information `at the manufacturer's website <https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/adc.html#_CPPv425adc1_config_channel_atten14adc1_channel_t11adc_atten_t>`__.
There's more information `at the manufacturer's website <https://docs.espressif.com/projects/esp-idf/en/v4.4.2/esp32/api-reference/peripherals/adc.html#_CPPv425adc1_config_channel_atten14adc1_channel_t11adc_atten_t>`__.
To simplify this, we provide the setting ``attenuation: auto`` for an automatic/seamless transition among scales. `Our implementation
<https://github.com/esphome/esphome/blob/dev/esphome/components/adc/adc_sensor.cpp>`__ combines all available ranges to allow the best resolution without having to compromise on a specific attenuation.
