Description: 1. Overview: MQ-6 Gas Sensor Module is a versatile and precise sensor designed to detect propane, butane, and LPG (Liquefied Petroleum Gas) gases. It's widely used in various applications, from industrial gas detection systems to hobbyist projects. 2. Design: The module consists of an MQ-6 sensor element, a heater for improving sensitivity, a voltage regulator, and a connection interface. Its compact size (approximately 30mm x 50mm) makes it easy to integrate into different systems. 3. Detection Principle: The MQ-6 sensor relies on the oxidation-reduction process of catalytic sensing elements to detect specific gases. Once a certain concentration of propane, butane, or LPG is present in the surrounding air, the resistance across the sensor changes accordingly. 4. Sensitivity: The MQ-6 module exhibits excellent sensitivity for the target gases, typically showing a significant change in resistance (>2x) when exposed to gas concentrations above 500ppm. This makes it an ideal choice fo
