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.
