After we have learned about the basics of the DHT11 sensor let us now see how to interface the DHT11 sensor with Arduino. Program virtual Arduino™ turtles like the Funduino and Zumo, simulate, test and debug in Proteus and then deploy on the real hardware with a button press. Connect VCC pin of DHT11 to +5v of Arduino. Simply you need to add the dht11 library. You can upload the following example code to your Arduino using the Arduino IDE. This was a small weekend experiment which I wanted to try for a long time. La curiosità mi ha spinto a misurare la temperatura e mi sono detto: basta un display 16x2 o 20x4, il sensore di temperatura DHT11 e il nostro Arduino UNO R3. I read thru Nathans Arduino code and see no reason why I couldn't re-use it.
