title: Getting NAN-Readings from DHT-11 Sensor
body: <p>I am trying to read temperature and humidity from a DHT-11 sensor with a arduino uno R3</p>
  
  <pre><code>#include &lt;DHT.h&gt;
  #include &lt;LiquidCrystal.h&gt;
  
  #define DHTPIN A3
  #define DHTTYPE DHT11
  
  DHT dht(DHTPIN,DHTTYPE);
  LiquidCrystal lcd(5,8,9,10,11,12);
  
  String hum="Humidity:";
  String temptext="Temp:";
  
  void setup() {
  
      Serial.begin(9600);
      lcd.clear();
      lcd.begin(16,2);
      dht.begin();
  }
  
  void loop() {
  
      float humidity = dht.readHumidity();
      delay(500);
      float temp = dht.readTemperature();
      delay(500);
        Serial.println(hum+humidity);
        Serial.println(temptext+temp);
        lcd.clear();
        lcd.print(hum + humidity);
        lcd.setCursor(0,2);
        lcd.print(temptext+temp);
        delay (5000);
  
  
  }
  </code></pre>
  
  <p>I am sure that my wiring is correct. What would be possible reasons for the DHT-11 reporting nothing but NAN? Might it be broken (I just unpacked it)?</p>
