Iraq is a developing country and so its developmental process has been stymied and often stalled, one obstacle is the lack of applying the latest technological innovations and instead relying on traditional methods. Wireless Sensor Networks (WSNs) is an emerging technology that have been utilized to make many improvements. This paper serves as a tutorial that aims at identifying some of the current WSNs applications that can be harnessed for aiding the development process in Iraq. It also discusses the advantages of wireless sensors in the context of Iraq and tackles the obstacles that may prevent their implementation. Finally, the paper presents a WSN system for salinity monitoring in the Iraqi rivers as it is one of the major issues in this country.
