Temperature and Humidity Sensor (DHT22) With Dexter Board

Dexter board is an educational trainer kit that makes learning electronics fun and easy. The board brings together all the necessary parts a beginner requires to change an idea to a successful prototype. With Arduino at its heart, a huge number of open source projects can be easily implemented directly on this board. Interactive features like on board LCD display, switches, motor drivers and LEDs' help make development faster and debugging easier.

Together with I2C and SPI pinouts, we have also integrated wireless protocols like Bluetooth on the board itself. This opens a whole spectrum of ideas to build creative IOT projects. Most importantly all these features are implemented on a single board thus all your projects are now portable, mobile and wireless.

Dexter Board can be used in wide variety of applications for training and development in domains such as embedded systems, robotics, practical electronics education, electronic hardware development and more...

Supplies:

· Dexter Board

· Ada-fruit DHT22 temperature sensor

· Resistor 10K

· Connecting wires

· Arduino Programming IDE

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Connect the Pins As in the Diagram

Step 2: Adding CH340G Driver

If you are using Arduino first time with Dexter then please install ch340g driver. Go to the link and follow the instructions

Download CH340G Driver

Step 3: Adding Ada-fruit Sensor Library

Now you have to add the adafruit sensor library to your Arduino ide. If you already have the library no need to download again, you can proceed to next step

Download adafruit_sensor library

Download the file as zip then

go to Arduino -- > Sketch-->Include Library-->Add .Zip Library

Then select the zip file you downloaded.

Your library is added to the Arduino Ide. You can see it at the bottom of your library list.

Step 4: Adding DHT Sensor Library

Now you have to add the library for you adafruit DHT senosr.

Download DHT-22 LIbrary

Repeat the above steps to add the library to Arduino ide.

Step 5:

Now Download this given Arduino code to your IDE.

Step 6: Compile and Upload Your Program to Dexter

Now,

From tools select the board as Arduino Uno, and also select the your port at tools-->port

Now compile and Upload the program

Step 7:

If your LCD display shows nothing,adjust your LCD’s potentiometer You will get the output as in the picture
