Summary of the Project Proposal
The goal of this proposed project aims to design, build, and test a wireless sensor for measuring lake Tana features such as the depth, water clarity, and pressure. This project is motivated by the need to keep the water of the lake clear, keep the life in the lake to be safe and have up to date information about the lake. To achieve this goal, this project will employ different building materials, such as transmitters, receivers, computers, wireless sensor nodes, storage and display units, as well as wireless communication technology to collect the data and display to the concerned body; hence this body takes measure according to the information submitted by using the overall process.
Statement of the problem
Lake Tana is the largest lake in Ethiopia, which is used as a home for different living things (such as fish hippopotamus, chorocodiles and others) and used for transportation. With this applications Lake Tana depth, water clarity and other features should be kept safe. But the amount of water in the lake fluctuates from season to season, and even if this time the water is thought to be clear the water can be polluted by human beings and different natural phenomena. These defects have risk on transportation and life of living things in the lake. In some seasons the water level reduces very much and this creates an opportunity for the boats to be crashed with stones. Also the water may be polluted due to different cases and it become risk for life in the water. Hence the concerned body or organization should have an up to date data about the lake. To have a daily information about the lake wireless network have a greater impact. These network can give the online data about the lake, such as the depth, acidicity of the water, pressure and other information to the concerned body or organization.
Organizational Background
Two third of the earth surface is covered by water bodies, such as oceans, lakes, seas, rivers, streams and others. These water bodies have plenty of uses, starting from usage for drinking and bath to usage for ecosystem and continent to continent transportation. These water bodies are the source of all life on earth, besides they are shelters for different living things. Hence the features of these bodies should be studied every time and the concerned bodies should have a full information about these water bodies.
Methodology
Procedure
As we have proposed earlier the design process includes gathering of the requirements, their analysis, the design of the solution, development of the software architecture, development of the code, testing, deployment and post implementation. First the data required about the lake Tana is gathered by consulting to the concerned bodies may Tana transport agency, Amhara Region Water Resource Agency or people living a round the lake. Then the device is selected that are appropriate for collecting data, such as the type of sensor used and memory amount for the WSNs is deduced. Depending on the type of the data to be gathered using software, the sensor node is selected and programmed using a program, OS applicable for wireless sensor, the design is developed and the code is tested. Using lab equipments available perform an experiment for the hall system. After this purchase all the devices required for the final implementation and test each of the devices and load the code to be installed to the microcontroller which controls the wireless sensor. After checking the devices the final design process is implementation.
Testing and Implementation
The test is performed in the laboratory of School of Computing and Electrical Engineering since there is availability of the required devices. The devices used to conduct this test as described earlier are sensors, microcontrollers, signal processors, transmitters, receivers, antennas and computer. Each of these components are assembled according to the design.
In implementation the real hard ware is installed, and started by installing sensors at different places on lake Tana and are used to sense different characteristics of the water such as the depth, the acidicity and others. This sensed signal is then adjusted by signal conditioners and become suitable for next manipulation. After this the signal is fed into a transceiver that is transmitter- receiver which manipulates the signal to be suitable for wireless transmission.
