Aquaculture, particularly fishpond farming, is essential for meeting global food demands
and sustaining livelihoods, but poor water quality often hampers productivity and increases
fish vulnerability to diseases. This study focuses on the development of a smart monitoring
system for fishpond management to address these challenges by enhancing efficiency,
sustainability, and production outcomes. The main objective of this study is to develop a
machine that measures temperature, pH level, and dissolved oxygen to increase the
production of fish and to take action immediately to prevent devastating loss. Powered by

solar energy and utilizing an Arduino Uno microcontroller, the system ensures eco-
friendliness and efficient data management. The test results indicated that water

temperature ranged from 26.19°C to 26.87°C, pH levels showed slight daily variations
between 6.21 and 6.58, and dissolved oxygen levels exhibited significant fluctuations,
particularly on Day 3 (9 mg/L to 14 mg/L and down to 6 mg/L). These findings highlight
the need for continuous monitoring to maintain optimal water quality. The system was
evaluated by 40 individuals, including fishermen, fishpond owners, engineers, students,
and fish vendors, who rated its performance as excellent with a mean score of 4.57. This
innovative solution offers a sustainable approach to fishpond maintenance, boosting
productivity and ensuring better-quality aquaculture products.
