Arduino source code for ESP32 internal temperature sensor and hall sensor

esp32_internal_hall.ino

void setup() {
  Serial.begin(115200);
}
 
void loop() {
 
    int measurement = 0;

    measurement = hallRead();
 
    Serial.print("Hall sensor measurement: ");
    Serial.println(measurement); 
 
    delay(1000);
}

esp32_internal_temperature.ino

#ifdef __cplusplus
extern "C" {
#endif
uint8_t temprature_sens_read();
#ifdef __cplusplus
}
#endif
uint8_t temprature_sens_read();

void setup() {
  Serial.begin(115200);
}

void loop() {
  Serial.print("Temperature: ");
  
  // Convert raw temperature in F to Celsius degrees
  Serial.print((temprature_sens_read() - 32) / 1.8);
  Serial.println(" C");
  delay(5000);
}

@kickass42zer0 Thanks for your implementation! To format code in Markdown, you need to enclose your code in between 3 backticks.

```
like so
second line etc.

Hello, I have change the Arduino sketch for internal temperature sensor ESP32 CPU little bit.
https://gist.github.com/An-Toha/5a53f4fbe571c1b9cf02b362a83e93df
(Don't know how properly put code here)
The main ideas are:
to ignore 53.3 (128 before converting to Celsius);
WiFi must be connected, if else you'll get 53.3 (128) only.
Tested in AI Thinker ESP32 Cam module. Can be add to standard camera example in Arduino.
While ESP32 Cam module was idle - the temperature was around 47C. One value per 10-15 sec while idle.
While camera video stream was on - the temperature was rising to around 57C.
See temperature values in serial monitor at 115200.
