DHT 11 Temperature and Humidity Sensor

DHT 11 sensor is Temperature and Humidity Sensor, fetch a value from the environment. DHT 11 Sensor is useful for making Weather Station like projects.

But in this project, you just learn how to fetch data from the environment using DHT 11 and display in Serial Monitor.

3 Steps then see the Magic

Step 1: Setup

We do not need to set up a bunch of tools just install Arduino IDE for Code, Debug, and Burn the Code into IC.

Step 2: Code

Step 3: Wiring

To develop this project we are going to use these components :

• Arduino Uno
• DHT 11 Sensor
• Breadboard
• Jumper Wire
