DHT11-org

This project uses DHT11 sensor module to get environment temperature and humidity and show them in serial monitor window.

Step 1: connect DHT11 sensor to Arduino as per following  pin map table:

DHT11 Pin Arduino Pin
VCC 5V
DATA D3
GROUND GND

circuit graph.

Step 2: Download DHT driver library from http://osoyoo.com/wp-content/uploads/samplecode/DHT.zip,unzip the file,
move the DHT folder to Arduino IDE library sub-folder

Step 3: Download sketch code and load it into Arduino IDE.

Result:

After running above code, open serial terminal upright corner of Arduino IDE, you will see temperature and humidity data as following video:
