Abstract:
"Water Pollution" is one of the environmental problems which has the direct effect and causes damage not only to population health, but also to the natural biological communities. The majority of water pollution causes include a sewage treatment plant, city storm drain or factory, which release the pollutants into water bodies without adequate treatment to remove harmful compounds such as lead, mercury, cadmium and cyanide The operation process will start from sensor node receive the information from Dissolved Oxygen sensor in which at the same time contains the temperature sensor. After that the information will be delivered to the control station which sends information to a database that can utilize report the result on a website. The control station can record the information onto SD Card to backup the information in case of any technical problems. A notification can be delivered to a person in charge if the system has any problem concerning to the quality of water. For example, if the dissolved oxygen value is less than 2mg/L, the system will notify the user in order to find a solution later on.
