    .. note::

        ESP32 does not have a built-in temperature sensor.

.. only:: esp32s2

    The ESP32-S2 has a built-in temperature sensor. The temperature sensor module contains an 8-bit Sigma-Delta ADC and a temperature offset DAC.
    The conversion relationship is the first columns of the table below. Among them, offset = 0 is the main measurement option, and other values are extended measurement options.

    +--------+------------------------+------------------------+
    | offset | measure range(Celsius) | measure error(Celsius) |
    +========+========================+========================+
    |   -2   |        50 ~ 125        |           < 3          |
    +--------+------------------------+------------------------+
    |   -1   |        20 ~ 100        |           < 2          |
