MQ-6 LPG Isobutane Propane Hydrogen Gas Sensor Module

The MQ-6 LPG Isobutane Propane Hydrogen Gas Sensor Module is a reliable and high-performance sensor designed to detect LPG, isobutane, propane, and hydrogen gases in the air. Built with a SnO₂ semiconductor gas-sensitive material, the MQ-6 responds quickly and accurately to even low concentrations of combustible gases, making it an excellent choice for home, industrial, and automotive gas detection systems.

Operating at 5V DC, this sensor module provides both analog (AO) and digital (DO) outputs, making it fully compatible with Arduino, ESP8266, ESP32, and Raspberry Pi. The onboard LM393 comparator IC and adjustable potentiometer allow you to fine-tune the detection threshold for digital output, making it suitable for projects requiring automatic gas alarms or IoT-based environmental monitoring.

The MQ-6 sensor’s high sensitivity to LPG, propane, and isobutane ensures accurate detection of gas leaks, while its low sensitivity to alcohol and smoke minimizes false alarms. With its fast response time, easy interfacing, and stable performance, it’s a go-to solution for makers, students, and professionals working on Arduino-based safety and automation systems.

Perfect for IoT applications, the MQ-6 can send real-time readings to connected devices for automatic ventilation control, alarm activation, or data logging. Designed for reliability, simplicity, and long lifespan, it’s a must-have for any smart gas detection project.
