Thank you for the heads up on the internal temperature sensor.

[@LifeWithMatthew]

If you're always getting a reading 53.33c, it means that the function temprature_sens_read() is returning a value of 128, Sensor not Present. Your ESP32 didn't come with an on board temperature sensor, not all of them do.

[@vantasy5335]

Thx very helpful

[@SunilRathod-wc9bx]

Where is mentioned that ESP32 has inbuilt temperature sensor?
Because I can't get proper reading. Only 53.33 at all.

[@asali-channel]

This is the internal or cpu's temperature sensor

[@LifeWithMatthew]

@SunulRathod-wc9bx I know this is 2 years later, but 53.33 means that the sensor is return a value of 128, Sensor not Present. Your ESP32 didn't come with an on board temperature sensor, not all of them do.

[@giovannyperez5183]

Hi the temp sensor no change always 53.33 C. I think that esp32 no have temp sensor accessible for measures external

[@asali-channel]

Yes, I think I might have mentioned this in the video but the internal temperature sensor of the ESP32 is indeed the reading of the CPU temperature (I think)

[@juliocosta5818]

Asali No temperature sensor on chip, so reading is always 128.

@@juliocosta5818 Greetings! I have bought an esp32 and i used a hair dryer on esp32 and the temp reaches 68°C so i stop blowing hot air; but i haven´t the "internal led" ... Maybe you need a newer version

[@ummuhanigul5531]

I need analog sensor libraries for sparkfun esp32 thing on arduino IDE .any links ?

[@RomanSklyar-su4br]

Just use
float temp = temperatureRead();
