include
define DHTPIN 2 // Define the pin where the DHT22 is connected
define DHTTYPE DHT22 // DHT22 (AM2302)
DHT dht(DHTPIN, DHTTYPE);
void setup() {
Serial.begin(9600);
dht.begin();
}
void loop() {
// Wait a few seconds between measurements.
delay(2000);
// Read humidity (percent)
float h = dht.readHumidity();
// Read temperature as Celsius
float t = dht.readTemperature();
// Check if any reads failed and exit early (to try again).
if (isnan(h) || isnan(t)) {
Serial.println("Failed to read from DHT sensor!");
return;
}
// Print the values to the Serial Monitor
Serial.print("Humidity: ");
Serial.print(h);
Serial.print(" %\t");
Serial.print("Temperature: ");
Serial.print(t);
Serial.println(" C");
}
```
