Thanks for the information. I hope you can turn it on again. Please consider the solution that I can only do something Arduino ;-) There are many high temperature locations that require additional cooling. By covering the ESP32 with the aluminum sheet, it may be warmer under the sheet than an extern...

Sorry , I ask again for the ESP32 internal temperature sensor. I've read the internet ;-) and found many blogs that get 128 ° F or 53.33 ° C as Arduino output. e.g. this code "espressif/esp32/arduino/sketchbook/ESP32_int_temp_sensor/ESP32_int_temp_sensor.ino" That the sensor is inaccurate, I can no...
