Temperature and Humidity in Arduino & NodeMCU

#include "DHT.h"
DHT dht;
void setup()
{
  Serial.begin(9600);
  Serial.println("Status\tHumidity (%)\tTemperature (C)\t(F)");
  dht.setup(4);
}
void loop()
{
  delay(dht.getMinimumSamplingPeriod());
  float humidity = dht.getHumidity();
  float temperature = dht.getTemperature();
  Serial.print(dht.getStatusString());
  Serial.print("\t");
  Serial.print(humidity, 1);
  Serial.print("\t\t");
  Serial.print(temperature, 1);
  Serial.print("\t\t");
  Serial.println(dht.toFahrenheit(temperature), 1);
}
