Raspberry Pi Pico Air Quality Monitor — Live OLED Gauge + Buzzer Alert
Real-time air quality monitor built with Raspberry Pi Pico, MQ2 gas sensor,
SSD1306 OLED display, and buzzer alert system.
The OLED shows a live speedometer-style gauge tracking smoke, LPG,
methane, and hydrogen levels in real time.
Buzzer triggers on poor air — continuous alarm on danger level.
No simulation. Real hardware. Real output.
🔧 Hardware Used:
→ Raspberry Pi Pico
→ MQ2 Gas Sensor
→ SSD1306 128x64 OLED Display
→ Passive Buzzer
