## Article

Auther's system connects your hardware to the Android device. A dht11 sensor is used with Arduino Uno to sense temperature and humidity of the environment. It sends the value to your Android device which is neatly displayed in the app. This system is very easy to build and is useful for real-time monitoring of a remote room with an amazing display.

You will need-

- Arduino Uno

- Arduino Ethernet Shield

- Dht11 Sensor

- Jumper wires*3 (male to female)

- Arduino IDE

- Blynk app

- Lan Cable
