🔌 Wiring Guide (Arduino Example)

• VCC → 5V

• GND → GND

• AO (Analog Out) → A0 (for gas concentration readings)

• DO (Digital Out) → D2 (for threshold-based alerts)

❗ Critical Note:

• Preheat continuously for 24–48 hours before first use for accurate readings.

• Use MQ6 Arduino libraries for calibration and ppm conversion.

⚠️ Safety & Usage Notes

• Not for life-critical systems (use professional detectors in homes/industries).

• Avoid high humidity & alcohol fumes (may cause false positives).

• Calibrate in clean air before exposure to LPG/butane.
