DEVELOPING AN AQUATIC ENVIRONMENT MONITORING SYSTEM USING ARDUINO

Lakes constitute essential habitats and food resources for diverse fish, aquatic life, and wildlife. But lake ecosystems are dynamic and should endure rapid environmental changes, often leading to a dramatic deterioration in their aesthetic, recreational, and aquatic ecosystem functions. A lake is an interwoven water environment where the chemical, physical, and biological properties all interact and influence one another. The health of the life in a lake is a product of the lake's physical and chemical nature. The importance of monitoring lake conditions has been overlooked. Among many parameters for monitoring water quality, pH, dissolved oxygen level, turbidity and temperatures have been recognized as the most significant. The concentration of dissolved oxygen in water plays a vital role in determining the type and number of organisms that live in a lake and is a good indicator of the lake’s overall health. These parameters undoubtedly play a significant role in creating the aquatic organism to either thrive or decimate accordingly.

In this study, an Arduino system was created to continuously monitor the essential ecological parameters such as temperature, pH and dissolved oxygen level with an early warning system using RGB LED light codes and a Thingspeak IoT communication. The Arduino system was housed in a floatable plastic container stably positioned with a buoyance and a weight. The system's effectiveness was evaluated using a blind test, which demonstrated that our system could correctly measure water quality.
