However, for busy individuals, this task is often neglected, causing the plants to dry out and eventually die. This study proposes an IoT-based automatic watering system designed to activate irrigation based on soil moisture readings. The system employs soil moisture sensors and the Blynk IoT platform for real-time monitoring and control. The experience results show that the automatic watering mechanism performs more effectively than manual watering, maintaining optimal soil conditions and ensuring plant health. Additionally, user can monitor system status remotely through a smartphone. The proposed system transforms an ordinary garden into a smart garden that support autonomous, efficient, and sustainable plant care. https://eej.aut.ac.ir/article_5888_0a54b19a13b6712dc04d1b49215423d8.pdf
