HYDRABOT: ARDUINO-BASED ROBOT FOR MEASURING CONDUCTIVITY AND TURBIDITY AS WATER QUALITY PARAMETERS

Water is essential to both bodies and the environment since it moves nutrients, waste products, and oxygen to and from cells and organs, supporting various actions and results across the state. Turbidity is the measure of the relative clarity of a liquid. According to Fondriest Environmental Learning Center (2019), turbidity is caused by suspended sediment, such as silt or clay, as well as organic or inorganic matter, such as algae, plankton, and decaying material. On the other hand, water conductivity is important because it can tell you how much dissolved substances, chemicals, and minerals are present in the water. Higher amounts of these impurities will lead to higher conductivity. These substances are toxic to aquatic life and humans, especially when present in high concentrations. O'Donnell (2019) reported that higher temperatures, in most cases, imply higher electrical conductivity. An increase in water temperature of one degree Celsius causes an increase in electrical conductivity of 2-3%. Furthermore, technology has impacted and changed society in significant ways. One of the products of technology that helped humans in their daily activities are robots. Robotics for Society (2021) stated that robots are used in multiple areas, significantly where they can alleviate strenuous tasks or complete missions that are dangerous for a human to undertake. Apart from being precise and consistent, robots can work in any environment, adding to their flexibility. Meanwhile Arduino is an open-source platform primarily used for building robots or electronics projects. It is small but packed with powerful features, such as IDE (Integrated Development Environment) software for writing and uploading code to the device and a programmable circuit board. It can drive motors, light-emitting diodes, sensors, and other components. On the other hand, water analysis is a method in monitoring water quality which is very expensive. With this issue, the researchers conducted this study to help the people know the water conductivity and turbidity of water by just placing the sensors in the water also the robot is affordable and it can measure simultaneously. This study will determine if the Hydrabot is accurate and precise in water analysis in terms of water conductivity and turbidity also the researchers will determine if there is a significant difference in the water quality of the readings from the water analysis and the Hydrabot in terms of water conductivity and turbidity.
