Description: 1. The MQ-2 Gas Sensor is a versatile and highly sensitive device designed for detecting various gases including Hydrogen (H2), Propane, LPG (Liquefied Petroleum Gas), Methane (CH4), Carbon Monoxide (CO), and Smoke. 2. It features a heated filament sensor that catalytically reacts with the target gases to generate an electrical signal proportional to gas concentration in the environment. 3. The sensor has a working voltage range of 5V DC and is suitable for microcontroller-based applications, allowing for easy integration into IoT systems. 4. It boasts a high sensitivity (up to 10 ppm for LPG) and fast response time (less than 6 minutes), making it an ideal solution for monitoring gas leaks or maintaining air quality in confined spaces. 5. The sensor can be connected using standard JST connectors, enabling easy wiring and straightforward communication with other components in IoT applications. 6. It offers adjustable sensitivity via a simple potentiometer setting, allowing users
