Abstract : The integration of Augmented Reality (AR) with the Internet of Things (IoT) represents a paradigm shift in home automation and indoor gardening. This research presents a comprehensive implementation of an AR-enabled Plant Watering System. By leveraging the NodeMCU ESP8266 microcontroller for data acquisition and the Unity/Vuforia engine for visualization, the system bridges the gap between raw sensor data and an intuitive user experience. Experimental results confirm a sensor accuracy of ±2°C for temperature and ±3% for soil moisture, achieving a 98% system uptime. This paper details the hardware-software synergy that allows users to interact with their biological environment through a sophisticated digital twin interface.

Keywords : Internet of Things (IoT), Augmented Reality (AR), NodeMCU ESP8266, DHT11, Precision Irrigation, Unity Hub, Vuforia, ThingSpeak, Cloud Analytics, Raspberry Pi, Smart Cities.
