ESP32-S2 Temperature Sensor =========================== Overview -------- .. only:: esp32 .. 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 | +--------+------------------------+------------------------+ | 0 | -10 ~ 80 | < 1 | +--------+------------------------+------------------------+ | 1 | -30 ~ 50 | < 2 | +--------+------------------------+------------------------+ | 2 | -40 ~ 20 | < 3 | +--------+------------------------+------------------------+ Application Example ------------------- Temperature sensor reading example: :example:`peripherals/temp_sensor`.
