i am note sure if the library you used supports DHt21. Try this code:-

#include <DHT.h>

#define DHTPIN D4     // Digital pin connected to the DHT sensor

#define DHTTYPE DHT21   // DHT 21 (AM2301)



DHT dht(DHTPIN, DHTTYPE); // Initialize DHT sensor.

void setup() {
  Serial.begin(9600);
  dht.begin();
}

void loop() {

float temp = dht.readTemperature();

float hum = dht.readHumidity();

Serial.println(temp);
Serial.println(hum);
}
