Project Description
The Arduino based Air Quality Monitoring System which integrates multiple sensors with a microcontroller to track environmental conditions. It measures parameters like Ammonia (NH3), sulfur (S), Benzene (C6H6), CO₂, CO, temperature, and humidity. Designed for both indoor and outdoor use, this system can help reduce health risks by enabling timely action in polluted environments.
