The Utilization of Date (Phoenix dactylifera) Pits and Raspberry Pi Pico in Making a Water Quality Management Device

Water quality remains a critical global issue, affecting health, ecosystems, and economies. The challenge of ensuring clean and safe water has intensified in the 21st century, aligning with Sustainable Development Goal (SDG) 6, which advocates for universal access to clean water and sanitation. SDG 12 further emphasizes responsible consumption and production, urging the development of sustainable, affordable solutions for environmental protection. In response, this study developed an affordable Water Quality Management Device utilizing date pits for filtration and a Raspberry Pi Pico for real-time monitoring. Using an experimental, quantitative approach, the device accurately measured pH, turbidity, and TDS, facilitating timely detection of contamination. Results demonstrated a significant reduction in contaminants, from 40.47 g/L to 23.87 g/L, and high accuracy with average discrepancies of 0.04 for pH, 0.03 NTU for turbidity, and 0.04 g/L for TDS. These findings support the device’s effectiveness and potential for application in low- resource settings. Future improvements include enhancing the filter design, using better absorbents, and integrating disinfection features.
