Hello Mr. Rui.
In Module 7 of ESP32 course, in place of DS18B20 Sensor I am using LM35 temperature. sensor. But it is giving wrong readings on display. What chane is required to be done in the Sketch for Android IED. I have already installed LM35 Library. I thing the “oneWire.h” library may be giving wrong readings. am I right?

Which readings are you getting? With the LM35 temperature sensor, you don’t need any library, you can simply read with the analogRead function…

I don’t have any sketch with the LM35, but you can use any example for the Arduino Uno with that sensor on an ESP32…
