ESP32-S2 Temperature Sensor
===========================
Overview
--------
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 |
+--------+------------------------+------------------------+
| 0 | -10 ~ 80 | < 1 |
+--------+------------------------+------------------------+
| 1 | -30 ~ 50 | < 2 |

* **FIFO space threshold or transmission timeout reached** - the interrupts on TX or Rx FIFO buffer being filled with specific number of characters or on a timeout of sending or receiving data. To use these interrupts, first configure respective threshold values of the buffer length and the timeout by entering them in :cpp:type:`uart_intr_config_t` structure and calling :cpp:func:`uart_intr_config`. Then enable interrupts with functions :cpp:func:`uart_enable_rx_intr` and :cpp:func:`uart_enable_tx_intr`. To disable these interrupts there are corresponding functions :cpp:func:`uart_disable_rx_intr` or :cpp:func:`uart_disable_tx_intr`.
* **Pattern detection** - an interrupt triggered on detecting a 'pattern' of the same character being sent number of times. The functions that allow to configure, enable and disable this interrupt are :cpp:func:`uart_enable_pattern_det_intr` and cpp:func:`uart_disable_pattern_det_intr`.
