  ESP32 Tutorial - DHT11/DHT22 (Temperature and Humidity Sensor)
  From https://www.youtube.com/watch?v=K98h51XuqBE


  // REQUIRES the following Arduino libraries:
  // - DHT Sensor Library: https://github.com/adafruit/DHT-sensor-library
*/

// Import library
// #include <DHT.h>
#include <DHT_U.h>

// Initialize library
// PIN 23 yellow wire, DHT22 sensor
// DHT dht(23, DHT22);
DHT_Unified dht(23, DHT22);

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  // Buit-in LED
  pinMode(2, OUTPUT);

  // Initialize object
  dht.begin();

  // delay(2000);
}

void loop() {
  // put your main code here, to run repeatedly:
  // Reusable data structure
  sensors_event_t event;

  // Get temp
  dht.temperature().getEvent(&event);

  // Store in variable
  float celsius = event.temperature;
  // Convert to F
  float fahrenheit = (celsius * 1.8) + 32;

  Serial.print("Temperature is ");
  Serial.println(fahrenheit);

  // LED on for 1/10 second
  digitalWrite(2, HIGH);
  delay(100);
  // LED off
  digitalWrite(2, LOW);


  // float temp = dht.readTemperature(true);
  // float humidity = dht.readHumidity();
  // Serial.print("Temp: ");
  // Serial.print(temp);
  // Serial.println("F");
  // Serial.print("Humidity: ");
  // Serial.print(humidity);
  // Serial.println("%");

  // delay(2000); // Get new temp every 2 seconds

  delay(5000); // Get new temp every 5 seconds

  // delay(60000); // new temp every 60 seconds / 1 minute
