WEATHER BOX USING ARDUINO ~THE EASIEST

Ever wanted to check the temperature outside?

Check the temperature & Humidity  around you with this Smart device!

Lets Get Started!

Step 1: HOW IT WORKS?

How Does it Work?
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.

Step 2: THINGS REQUIRED

Things Required

>Arduino Uno  (Buy From Amazon.in) (Buy From Amazon.com)

>DHT11 ~ Temperature and Humidity Sensor

(Buy From Amazon.in)(Buy From Amazon.com)

>16*2LCD SCREEN (Buy From Amazon.in)(Buy From Amazon.com)

>POTENTIOMETER  (Buy from Amazon.in)(Buy From Amazon.com)

>JUMPER WIRE [male to female & Female To Female]

(Buy from Amazon.in)(Buy From Amazon.com)

> Header Pin [optional] (Buy from Amazon.in)(Buy From Amazon.com)

> Glue Gun [optional](Buy from Amazon.in)(Buy From Amazon.com)

Step 3: USING HEADER PIN

 

Use header pin so that You can easely make this project using only MALE TO FEMALE & FEMALE TO FEMALE JUMPER WIRES

Step 1: Place the Header Pin into the pins of Arduino After it glueing it will look like this.

Step 2:Using GlueGun, Glue the header pin to Arduino so that it does’nt become loose.

Double check whether the header pins are not loose,otherwise there will be no output from the pin!!!

Solder Header Pins to LCD SCREEN

Step 4: Take an old plastic box

Make holes for the LCD Screen and the DHT11 sensor using a Thermocol cutter (paper knife)

Step 4: CIRCUIT

CONNECT ARDUINO ACCORDINGLY!

DOUBLE CHECK!

Step 5: DHT11 Datasheet

Datasheet for DHT11

Please download the DHT library from the above link.

Then Open Arduino IDE Go to Sketch –> Include Library –> Add Zip File Close the Arduino IDE and open it again then you will find the library included.

For more info : https://www.arduino.cc/en/Guide/Libraries

Step 6: Code

Code

Download the Code from the link and open it with Arduino IDE.

Step 7: Done!

 

You can see the Current Weather on the LCD screen….

You can adjust the contrast (Sometimes the display might be blured)by turning shaft of the Potentiometer!

Thats all makers! If you have any doubts just comment it with the tag ” #MM ” Stay Tuned for more Projects!
