Built around the MQ6 sensing probe, the module provides analog signal output proportional to gas concentration, enabling reliable monitoring in safety and automation systems. High sensitivity to LPG-related gases combined with low response to alcohol vapor, cooking fumes, and cigarette smoke improves detection accuracy in real environments. A Gravity connector simplifies integration with development platforms and prototyping hardware, making the sensing board suitable for rapid deployment in embedded monitoring and control projects.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eMQ6 Gas Sensing Element for LPG Detection\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe gas sensing board uses an MQ6 semiconductor probe optimized for detecting propane, iso‑butane, and LPG concentrations. This sensing element offers strong selectivity toward common fuel gases while maintaining lower sensitivity to alcohol vapor and smoke interference. Such characteristics make the module well suited for leakage detection systems in kitchens, industrial storage areas, and fuel-handling facilities. Fast response characteristics allow the analog signal to quickly reflect changes in gas concentration, supporting real‑time monitoring and safety alarm systems.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAdjustable Sensitivity with Analog Output\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eAn onboard potentiometer allows precise adjustment of detection sensitivity to suit different monitoring environments. The analog output signal changes proportionally with gas density, enabling straightforward integration with microcontroller ADC inputs for continuous measurement. This adjustable calibration capability supports both early‑warning gas detection and threshold‑based alarm systems. Simple circuitry and stable operation contribute to long service life in continuous monitoring scenarios.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eGravity Interface for Rapid Prototyping\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe sensing module integrates a Gravity connector that enables plug‑and‑play wiring with compatible expansion boards.
