 - **raw** (*Optional*): Allows to read the raw ADC output without any conversion or calibration. See :ref:`adc-raw`. Defaults to ``false``.
 - **samples** (*Optional*): The amount of ADC readings to take per sensor update. On the ESP32 this value is ignored if ``attenuation`` is set to ``auto``. Defaults to ``1``.
+- **sampling_mode** (*Optional*): Sampling method to use when multiple samples are taken.

+  - ``max`` maximal value from all samples

 - **update_interval** (*Optional*, :ref:`config-time`): The interval
   to check the sensor. Defaults to ``60s``.
