Smart watering for a greener tomorrow, because every drop matters.
Negros Oriental State University (NORSU) proudly submitted to the World University Rankings for Innovation (WURI) our Category C5 entry: Sensor-Based Plant Watering and Monitoring System Using Arduino Featuring UPS.
Built to support tree-planting and reforestation efforts, this innovation solves the problem of inefficient manual watering by automating irrigation based on real-time soil moisture, so plants get exactly what they need, no overwatering, no underwatering. Even during power interruptions, the UPS feature keeps the system running, reliable and ready for real-world conditions.
What makes us proud: the system achieved high soil moisture detection precision (93.83% to 95.59%) and helped maintain an average moisture level of 45.8% after watering, proof that sustainability can be both smart and measurable.
This success belongs to our students and teachers.
To our student innovators who designed, built, tested, calibrated, and validated the prototype, thank you for choosing purpose-driven engineering. And to our teachers and mentors who guided the process with expertise, patience, and belief, thank you for shaping innovators who create solutions that truly serve.
