Water Quality Monitoring System Using 3G Network
Keywords:3G Communication, Database, Environmental Monitoring, Power System Computing,
AbstractThis paper presents a water quality monitoring system through the acquisition of data parameters such as temperature, pH level, turbidity, and amount of dissolved oxygen. The prototype consists of hardware such as sensors, Gizduino, Raspberry Pi, and 3G Pocket Wifi. Software element includes Raspbian as an operating system, Python as a programming language and MySQL for the database. The power source of the prototype comprises a battery and a solar panel. The testing of the prototype was done in three different bodies of water such as tap water, “Wawa” dam water and “Pasig” river. The raw data gathered from the testing were validated using calibration methods for the temperature sensor and pH sensor while the turbidity sensor follows the ISO 7027 and for the dissolved oxygen parameter, interpolation with the temperature values was computed. Also, the results revealed a minimal standard deviation for each of the parameters for all of the testing done from three bodies of water which validates the consistency of the data gathered. In terms of power supply, no power failure was encountered during the three testing sites. The data from the sensors were also transmitted to the database using MySQL through a 3G network.
