MQ-6 LPG, Isobutane, and Propane Gas Sensor Module

Product Description

Secure your home or workspace against gas leaks with the MQ-6 LPG, Isobutane, and Propane Gas Sensor Module. This high-sensitivity semiconductor sensor is specifically engineered to detect concentrations of combustible gases commonly used in domestic and industrial environments. At Robogears, we recommend the MQ-6 for its excellent resistance to interference from alcohol and cigarette smoke, ensuring a low false-alarm rate. The module features an LM393 comparator for stable digital switching and a multi-turn potentiometer to set your safety thresholds. Whether you are building an automated kitchen safety shutter or a portable gas detector at your Pimpri facility, the MQ-6 provides a reliable, fast-response solution for monitoring explosive gas levels.

Detailed Key Features

• LPG & Propane Optimized: Highly sensitive to Liquefied Petroleum Gas (LPG), Isobutane, and Propane, providing early warning for potential fire hazards.

• Dual Signal Interface: Features a Digital Output (DO) for direct triggering of buzzers or relays, and an Analog Output (AO) for real-time concentration measurement via an ADC.

• Adjustable Sensitivity: The integrated potentiometer allows you to calibrate the exact gas level at which the digital alarm activates, compensating for different environmental conditions.

• Fast Response & Recovery: The SnO2 sensing layer reacts almost instantly to the presence of combustible gases and clears quickly once the air is clean.

• Plug-and-Play Design: Standard 4-pin interface ensures easy connection to Arduino, ESP32, Raspberry Pi, and other common development platforms.

All Technical Details

• On-board Processing: The LM393 ensures the digital signal is sharp and free from the jitter often found in raw analog sensors.

• Visual Status LEDs: Includes a Power LED (Red) and a Signal LED (Green) that lights up the moment gas levels exceed your preset limit.

• Mounting Holes: Features a 3mm pre-drilled hole for secure installation in custom safety enclosures.

• Applications: Residential gas leakage alarms, industrial combustible gas monitors, and smart home IoT safety nodes.
