The MQ-2 gas sensor is an essential component for any Arduino or ESP8266 project involving gas detection. This microcontroller sensor module is designed to detect combustible gases like LPG, butane, propane, methane, alcohol, hydrogen, and smoke. With its high sensitivity and fast response time, it can accurately measure gas concentrations in the air, making it ideal for applications such as gas leakage detection, indoor air quality monitoring, and fire alarms. The module is easy to integrate with Arduino, ESP8266, or ATmega328P microcontrollers, allowing you to build sophisticated gas detection systems. Its compact size (40mm x 20mm x 15mm) and lightweight (9 grams) make it suitable for portable and space-constrained projects. Whether you're a hobbyist, maker, or professional developer, the MQ-2 gas sensor module is an indispensable tool for creating innovative gas detection solutions.
