To test the code, simply follow the usual procedure of compiling it and uploading it with the Arduino IDE, after the wiring between the sensor and the ESP32 is done. Once the procedure finishes, open the Arduino IDE serial monitor. You should get an output similar to figure 1, where the...
// NOTE: If using a board with 3.3V logic like an Arduino Due connect pin 1 // to 3.3V instead of 5V! // Connect pin 2 of the sensor to whatever your DHTPIN is // Connect pin 3 (on the right) of the sensor to GROUND (if your sensor has 3 pins) ...
