چکیده :

Smart irrigation systems are increasingly adopted in precision agriculture and indoor plant care to reduce water waste and human dependency [1], [2]. This paper presents the design and implementation of a low-cost, pot-level smart irrigation prototype built on Arduino UNO with a soil moisture sensor (YL-69), a DHT11 temperature–humidity sensor, LDR-based light sensing, and a solenoid valve for irrigation actuation. The primary contribution is a data-logging–centric design that persistently records multi-sensor environmental telemetry and irrigation activity onto a MicroSD card, enabling post-hoc quantitative evaluation and data-driven extensions (e.g., correlation analysis, anomaly detection, and learning-based scheduling) [4], [8], [9]. The system uses hysteresis threshold control to autonomously activate irrigation when dryness surpasses a defined threshold and stop watering once sufficient wetness is restored. An indoor deployment on Dracaena deremensis (‘Warneckii’) demonstrates stable operation without user intervention. Beyond demonstrating functionality, the logged dataset enables measurable assessment of moisture regulation, irrigation duty cycle, baseline comparisons against a simpler controller, and environmental influences on soil moisture dynamics, strengthening the system’s value as a reproducible research and educational IoT platform.
