MQ-2 Flammable Gas & Smoke Sensor Module for Arduino
The MQ-2 Flammable Gas and Smoke Sensor Module is a popular Arduino-ready sensor for detecting smoke and common flammable gases in DIY safety and monitoring projects. It outputs a signal you can read to trigger alerts, turn on a fan, log air quality changes, or build simple leak detection demos. It is a strong fit for STEM learning and prototyping, but it should be treated as a hobby sensor and not a replacement for certified home safety devices.
