# Steps
## AIR HUMIDITY AND TEMPERATURE Sensor Interface
media: 

notes: SETUP:
1. Put the RHT03(DHT22) sensor to the breadboard

2. Prepare the wiring connection as follows.

## ARDUINO + RHT03
media: http://s28.postimg.org/hbc51ksf1/hackpad_com_0_Re2o_WBULh_M_p_107637_1390227262595_A.jpg

notes: 3. Make sure that you connected the yellow jumper wire to "pin 2" in Arduino from one side 
    and on the second row for the sensor (from the left side) in the breadboard
5. If everything went right, you will find your connection similar to the following:

notes: 4. You can use a resistor of 10K ohm as pull up resistor 
    Notice: the resistance has to exceed 4.7K ohm
Reference Link: http://garagelab.com/profiles/blogs/tutorial-humidity-and-temperature-sensor-with-arduino

## SOFTWARE SETUP:
media: undefined

notes: 1-Download the Arduino libraries from the following link:
https://github.com/markruys/arduino-DHT
Notice: This link includes libraries that are generic for DHT sensors (i.e DHT11 and   
                   9DHT11 and DHT22) 
2. Unzip the folder into anywhere.
3. Make a new folder called "arduino_DHT" in the following destination:
C:\User\yourUSER\Documents\Arduino\libraries
4. Copy the content of the downloaded folder (i.e. after unzipping) to the new folder
    "arduino_DHT" 
5. Open the file "DHT.h" in a notepad 
6. Replace "Wprogram.h" with "Arduino.h" and save the file
7. Then, open Arduino program to load the code file from:
C:\User\yourUSER\Documents\Arduino\libraries\arduino_DHT\examples\DHT_Test
8. Verify the code by clicking on the following button "Verify" :

notes: 9. Now, your code is compiled and ready. Connect the Arduino with your laptop through the 
    USB cable
10. You have to "upload" the code into the Arduino by clicking the "Upload" button, and wait till a message appear saying "Upload completed"
i.e. This means that your code have been successfully uploaded into the Arduino Chip.
11. To monitor the data out of the sensor, click on "Serial Monitor" on the top right of the  
      Arduino window.
12. If everything went right, you will see the the following results:

notes: Notice: These data are based on the local temperature and humidity. So, make sure to verify your results by checking the local temperature and humidity at your place.

## Carbon Monoxide sensor [MQ-7]
media: undefined

notes: Description of the Carbon monoxide:

 Carbon monoxide is a product of incomplete combustion of organic matter due to insufficient oxygen supply to enable complete oxidation to carbon dioxide (CO2). It is often produced in domestic or industrial settings by older motor vehicles and other gasoline-powered tools, heaters, and cooking equipment. Exposures at 100 ppm or greater can be dangerous to human health.

## HARDWARE SETUP:
media: undefined

notes: Note: we can remove the transistor (2N3904) because this relay can work easily with 5v and current  from Arduino board (we have removed it in our circuit) this depend on the type of the relay.

notes: 1.Download MQ-7 library from here:
    https://github.com/jmsaavedra/Air-Quality-Egg/tree/master/libraries/CS_MQ7.
2.copy and paste the downloaded library file in the libraries folder in the pass of the  program if you use :
   linux : it will be at /home /your account name/sketchbook/libraries
   windows :it will be at  the file of Arduino because it's Portable you can find it at           
              libraries file .
3.open the example file using Arduino >>>>go to file-->examples-->Cs_MQ7  
4.run the project.

notes: 1.we now have combined both of modules on the same program
   Note: make sure that you put the new project which will contain this code on the library file to be shown on example tab under file tab on arduino program
2.  Library code: download it from the following link and copy it into the library folder
https://drive.google.com/file/d/0B2uQ5MUyXb6mNnJUZ1FEWU5ERXc/edit?usp=sharing

Unzip the folder into anywhere.\n3. Make a new folder called \"arduino_DHT\" in the following destination:\nC:\\User\\yourUSER\\Documents\\Arduino\\libraries\n4. Copy the content of the downloaded folder (i.e. after unzipping) to the new folder\n    \"arduino_DHT\" \n5. Open the file \"DHT.h\" in a notepad \n6. Replace \"Wprogram.h\" with \"Arduino.h\" and save the file\n7. Then, open Arduino program to load the code file from:\nC:\\User\\yourUSER\\Documents\\Arduino\\libraries\\arduino_DHT\\examples\\DHT_Test\n8. Verify the code by clicking on the following button \"Verify\" :</p>\n\n<h2>undefined</h2>\n\n<p>{{5}}</p>\n\n<p>notes: 9. Now, your code is compiled and ready. Connect the Arduino with your laptop through the \n    USB cable\n10. You have to \"upload\" the code into the Arduino by clicking the \"Upload\" button, and wait till a message appear saying \"Upload completed\"\ni.e. This means that your code have been successfully uploaded into the Arduino Chip.\n11. To monitor the data out of the sensor, click on \"Serial Monitor\" on the top right of the <br>\n      Arduino window.\n12. If everything went right, you will see the the following results</p>\n\n<h2>undefined</h2>\n\n<p>{{6}}</p>\n\n<p>notes: Notice: These data are based on the local temperature and humidity.
