This project integrates real-time CO2 and temperature sensor data with a 3D Unity visualization and the IFGI Digital Twin. It includes interactive UI elements for enhanced data exploration.
- Real-time CO2 and temperature data acquisition using ESP32 sensors
- Interactive 3D visualization in Unity
- Integration with IFGI Digital Twin for spatial context
- UI for switching between CO2 and Temperature visualization
- Supports multiple sensor inputs
- ESP32 SenseBoxMCU
- CO2 Sensor – Sensirion SCD30
- Temperature Sensor – HDC1080
- Optional: OLED Display, LED Matrix, and other peripherals
- Unity 3D
- IFGI Digital Twin platform
- Arduino IDE for ESP32
- Unity plugins for real-time data fetching
-
Direct Mapping
Each sensor location in Unity changes its color (green/yellow/red) to reflect the measured CO₂ level and green/yellow/blue for temperature. This mirrors a traffic light metaphor in 3D for intuitive visualization. -
3D Interpolation (Inverse Distance Weighting – IDW)
Instead of showing only point values, the room volume is sampled into a grid. Each grid point’s value is interpolated from the deployed sensors using IDW. Voxels/tiles are generated and colored based on interpolated CO₂ or temperature. Users can switch between CO₂ mode and Temperature mode via the UI. -
2D Plane Heatmap
A horizontal slice of the room is generated (front, middle, back) using the UI. This allows top-down heatmap analysis of a single floor layer.
- Connect your ESP32 to the CO2 and temperature sensors.
- Upload the
.inoArduino sketch to your ESP32 using Arduino IDE. - Open the Unity project.
- Configure the real-time data plugin to connect to your ESP32 sensors or IFGI Digital Twin endpoints.
- Run the Unity scene to visualize live sensor data with interactive UI.
