MQ-6 LPG Sensor

The MQ-6 LPG Gas Sensor Module is a reliable gas detection sensor designed to detect Liquefied Petroleum Gas (LPG), propane, and butane in the surrounding air. It uses a sensitive SnO₂ (tin dioxide) sensing layer that changes its conductivity when exposed to combustible gases, allowing accurate detection of gas leaks.

This module provides both analog output (AO) for measuring gas concentration levels and digital output (DO) for threshold-based detection. The onboard LM393 comparator allows users to set a trigger level using a built-in potentiometer, making it suitable for alarm and safety applications.
