 The {IDF_TARGET_NAME} has a built-in sensor used to measure the chip's internal temperature. The temperature sensor module contains an 8-bit Sigma-Delta analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) to compensate for the temperature measurement.
 
-Due to restrictions of hardware, the sensor has predefined measurement ranges with specific measurement errors. See the table below for details.

-    The temperature sensor is designed primarily to measure the temperature changes inside the chip. The internal temperature of a chip is usually higher than the ambient temperature, and is affected by factors such as the microcontroller's clock frequency or I/O load, and the external thermal environment.
+    The temperature sensor is designed primarily to measure the temperature **inside** the silicon. The sensor can reflect the temperature changes very well but it can't give a precise measurement value. So it's not recommended to use it for ambient temperature measurement.
