This project uses a DHT11 temperature and humidity sensor with the three pin but you can also use any other sensor the changes in the code should be as per the model. I have used Arduino UNO for this project.
DHT sensor with the Arduino board
| DHT 11 | Arduino uno |
| VCC | 5V |
| DATA | D4 |
| GND | GND |
LCD and Arduino uno connections
| LCD | Arduino uno |
| SDA | SDA(A4) |
| SCL | SCL(A5) |
| VCC | 5V |
| GND | GND |

So now you can measure real time environmental data and you can display it in real time
