🔌 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.
