Water tester with security alarm / Noor Aziroh Azizan and Marhanim Abu Bakar

Water Tester with the Security alarm is designed to restore and maintain the chemical, physical and biological integrity of our nation’s water. The mission of this program is to maintain and improve the quality of our streams, lakes and ground water for the benefit of present and future generations. In this thesis, we use infrared receiver and water tester sensor to make a new detection by combining both circuits. This project can be use at many places. As and example we can put it in the river to detect water pollution. This project also can be put in swimming pool to make sure the quality of the water. It can give benefits to agricultural sector too. This project will operate when the sensor get result of the water are bad. That’s means the water are polluted. Then, the speaker will give a sound. From the sound, we can know the water had been polluted. The project that we made just use a small budget to complete it because it is just a sample. It may be use a big cost to reliable it to'a big structure plan that mentioned above. Although it will expend a big budget, we believe that it will produce many advantages
