# Temperature Sensor Example
The ESP32-S2/C3/S3 has a built-in temperature sensor. The temperature sensor module contains an 8-bit Sigma-Delta ADC and a temperature offset DAC.
The ESP32-S2/C3/S3 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 two columns of the table below. Among them, `offset = 0`(default) is the main measurement option, and other values are extended measurement options.
