Revolutionary Combination of Metaverse and IoT

This project integrates Internet of Things (IoT) hardware control with a virtual reality (VR) interface powered by a Raspberry Pi 5 running Raspbian OS. The core system architecture utilizes an Apache web server running PHP to host a control interface accessible via a VR browser or a VR VNC app on a smartphone placed inside a VR Box or Google Cardboard headset, paired with a VR Controller. When a user interacts with the virtual environment, HTTP requests are sent to the PHP backend hosted on the Raspberry Pi. The server then executes underlying scripts that interface with the GPIO pins using the Wiring-Pi library. These digital signals drive low-voltage components like an LED and control a Solid State Relay (SSR). Because an SSR uses optoisolation, the low-voltage DC signal from the Raspberry Pi safely triggers the switching of high-voltage alternating current (AC) to power an AC bulb. Additionally, an Light Dependent Resistor (LDR) is integrated into the circuit to monitor ambient light levels, allowing the system to capture real-world sensory feedback and report it back to the network. Through this closed-loop setup, users can toggle physical appliances from inside an immersive virtual reality space while simultaneously monitoring the physical environment's sensor states.
