# Steps
## 1-ARDUINO + RHT03
media: http://www.deviantsart.com/3ldcetl.jpg

notes: Connect the RHT03(DHT22) sensor to the breadboard.
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 readboard.

## If everything went right, you will find your connection similar to the following:
media: http://www.deviantsart.com/3b8m0is.jpg

notes: -You can use a resistor of 10K ohm as pull up resistor .
-Notice: the resistance has to exceed 4.7K.
-Reference Link:

## 1-(a) SOFTWARE SETUP: 1)Download the Arduino libraries from the following link:https://github.com/markruys/arduino-DHT
media: undefined

notes: Notice: This link includes libraries that are generic for DHT sensors (i.e DHT11 and DHT11 and DHT22)

## 1- (a) 2) Unzip the folder into anywhere
media: undefined

notes: -Make a new folder called "arduino_DHT" in the following destination:C:\User\yourUSER\Documents\Arduino\libraries

## 1- (a) 3) Copy the content of the downloaded folder (i.e. after unzipping) to the new folder  "arduino_DHT"
media: undefined

notes: undefined

## 1- (a) 4) Open the file "DHT.h" in a notepad.
media: undefined

notes: -Replace "Wprogram.h" with "Arduino.h" and save the file

## 1- (a) 5) Then, open Arduino program to load the code file from:C:\User\yourUSER\Documents\Arduino\libraries\arduino_DHT\examples\DHT_Test
media: http://www.deviantsart.com/a7773g.png

notes: -Verify the code by clicking on the following button "Verify" in the last image.Now, your code is compiled and ready.

## 1- (a) 6)Connect the Arduino with your laptop through the USB cable.
media: undefined

notes: -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.

## 1- (a) 7)To monitor the data out of the sensor, click on "Serial Monitor" on the top right of theArduino window.
media: undefined

notes: If everything went right, you will see the the following results:

## 1- (a) 8) Output
media: http://www.deviantsart.com/3q7i1ss.png

notes: 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.

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

notes: 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.

## 2- schematic of sensor board
media: http://www.deviantsart.com/25s76ov.png

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.
