Arduino-Powered Precision Air Quality Control for Healthier Living
Experience professional-grade air purification with our AI Smart Air Purifier. Powered by Arduino Uno and advanced MQ135 sensor technology, it intelligently monitors and cleans indoor air by detecting pollutants like CO2, smoke, VOCs, and more. Dual HEPA + Carbon filtration removes 99.97% of 0.3ฮผm particles and odors, covering up to 200 sq ft effectively.[web:24][web:29]
Real-time AQI display, color-coded alerts, and automatic fan activation ensure your air stays clean 24/7. Compact, energy-efficient (12V operation), and fully customizable.
MQ135 sensor samples air every second, calculates AQI (0-500), displayed on OLED screen.
120mm DC fan + relay turns ON automatically when AQI > 100. Air flows through HEPA + Carbon filters.
RGB LED: Green (Good), Yellow (Moderate), Red (Poor). Buzzer alerts at AQI > 150.
0.96" display shows AQI, raw PPM, fan status, and pollution level in real-time.
Self-adjusts to baseline clean air. PWM fan speed scales with pollution severity.
12V adapter + buck converter. Sleep mode when AQI < 30. Low power consumption (~5W max).
Explore the Smart Air Purifier in immersive 3D! Rotate, zoom, and interact with all components in real-time. Simulate different AQI levels, watch the fan activate, and see the complete system in action with live sensors, wiring, and airflow visualization.
