The busy lifestyle of urban residents often limits their time and opportunities to engage in gardening or farming activities at home. To address this, an automated plant irrigation system for vertical gardens was developed based on the Internet of Things (IoT) with the aim of facilitating gardening activities at home. The system employs an ESP32 microcontroller as the main controller, equipped with a soil moisture sensor, a temperature sensor, and the Blynk application for real-time monitoring accessible via Android devices or a web interface. Testing was carried out by comparing sensor readings with standard measuring instruments to determine accuracy, as well as functional testing of the monitoring and control system. The system was designed to maintain soil moisture within a range of 40–60% and the ambient temperature around the plants within 25–35°C. Experimental results showed an average error of 4.29% for soil moisture sensor readings and 5.69% for temperature sensor readings. Furthermore, the monitoring function test using Blynk successfully displayed real-time data with a 100% success rate, ensuring that soil moisture and temperature conditions could be controlled as needed. In the future, this research could be further developed by adding efficiency analysis, economic value assessment, and evaluating the system’s overall power consumption.
