Project Idea
Create a smart IoT-based system that monitors air quality in real-time, detecting harmful gases, particulate matter, temperature, and humidity to ensure a healthier living environment. This solution provides instant alerts, data visualization, and long-term air quality trends for informed decision-making.
Project Description
The Smart Air Quality Monitoring System integrates multiple sensors with a microcontroller and cloud connectivity to track environmental conditions. It measures parameters like Ammonia (NH3), sulfur (S), Benzene (C6H6), CO₂, CO, temperature, and humidity. Data is uploaded to a cloud platform for live monitoring and historical analysis. Users can access information via a mobile app or web dashboard and receive alerts when air quality drops below safe levels. Designed for both indoor and outdoor use, this system can help reduce health risks by enabling timely action in polluted environments.
