We are going to get to know the DS18b20 temperature sensor with ESP32-S2 Franzininho WiFi, a sensor that communicates with the microcontroller via one wire
Let’s see how to use ESP32-S2 to publish in the cloud using Thingspeak; we will send the ESP32-S2 internal temperature sensor to it
Come with me to learn how to use the ESP32-S2 internal temperature sensor, with the Arduino IDE and printing on a serial monitor
Learn how to program a board based on ESP32-S2 Franzininho with Arduino IDE, doing both the blink LED and Wi-Fi server examples
Learn how to use the Franzininho Wi-Fi, an educational board based on the ESP-S2, programmed in micropython
