Indoor air quality is crucial for maintaining a healthy living and working environment. HibouAir is a powerful air quality monitoring device that provides real-time data on CO2 levels, temperature, humidity, and air pressure.
This project demonstrates how BleuIO enables communication with HibouAir, allowing real-time environmental data to be retrieved, while Google’s Gemma model processes and analyzes the data to provide meaningful, easy-to-understand responses through a chat interface.
Users can interact with HibouAir’s smart assistant and ask questions such as:
- “What is my room temperature?”
- “What is the humidity level?”
- “How is the air quality in my room?”
The system retrieves real-time sensor data from HibouAirand provides contextual recommendations based on environmental conditions.
By leveraging Google’s lightweight Gemma model, this project ensures efficient and intelligent analysis of air quality data, making it accessible for various applications, from smart homes to research.
Features of This Project- Live CO2, Temperature, Humidity, and Pressure Monitoring
- Google-Powered Analysis for Meaningful Insights
- Conversational Chat Interface (“Chat with HibouAir”)
- Completely Local – No Internet Required
- Lightweight & Efficient Processing with Gemma
We need:
- BleuIOfor Bluetooth communication.
- Ollamato run Google’s Gemma model locally.
- HibouAirfor air quality monitoring
- Gemmafor efficient data analysis and meaningful responses.
Install Python Dependencies
pip install flask bleuioInstall Ollama (For Local Processing)For Mac/Linux:
curl -fsSL https://ollama.com/install.sh | shFor Windows, download it from Ollama’s official site.
Install Google’s Gemma Model
ollama pull gemmaFor this project, we chose Gemma, a lightweight, open-source model developed by Google, because it aligns with Google’s ecosystem and provides efficient, real-time insights for environmental data.
Why Use Google’s Gemma?- Optimized for Efficiency – Runs well on low-power machines without requiring cloud resources.
- Google-Backed & Open Source – Developed by Google DeepMind, ensuring high-quality performance with full transparency.
- No API Costs & Fully Local – No need for an internet connection or paid APIs, making it a cost-effective solution.
- Designed for Meaningful Responses – Processes real-time air quality data and provides insightful, structured feedback.
- Phi-2 – Even lighter but lacks detailed contextual understanding.
- Llama3 – More powerful but requires more computational resources.
- Mistral – Previously used, efficient, but not part of the Google ecosystem.
HibouAir continuously broadcasts CO2, temperature, humidity, and pressure via Bluetooth. We use BleuIO to scan and retrieve these values in real-time.
Setting Up the Chat InterfaceUsers can type questions like:
- “What is the temperature?”
- “What is my CO2 level?”
- “How is the air quality?”
The system fetches real-time sensor data from HibouAir and provides Google-powered analysis and recommendations.
app.py (Backend)- This script:
- Scans for HibouAir data
- Extracts CO2, temperature, humidity, and pressure
- Uses Google’s Gemma model for intelligent responses
- Serves the chat interface via Flask

Based on these readings, the air quality is good.The web interface allows users to ask about specific values like temperature, humidity, pressure, CO2, or overall air quality.
Output
This project is open-source! You can access the full code and modify it for your own needs.
This project showcases how HibouAir and BleuIO can be integrated to provide real-time air quality analysisin a way that is easy to understand. Instead of requiring users to interpret raw sensor data, the chat interface translates complex air quality values into clear, meaningful insights. Powered by Google’s Gemma model, it delivers simple and actionable responses—helping users understand their indoor air quality without needing to be experts.
