MINIMUM TECH FEATURES

• Model: MQ-6
• Operating Voltage: 5V DC

DESCRIPTION

• The MQ-6 Gas Sensor is designed for detecting LPG, propane, and butane gases with high sensitivity.
• It reacts quickly to changes in gas concentration, enabling real-time leak detection.
• Based on SnO₂ (tin dioxide) semiconductor technology, the sensor shows low conductivity in clean air and higher conductivity when exposed to combustible gases.
• Provides both an analog output (for precise readings) and a digital output via an onboard comparator for threshold-based alarms.
• Features fast response and recovery, making it suitable for safety applications.
• Built for long-term stability with minimal drift.
• Consumes low to moderate power, suitable for portable detectors and compact devices.
• Includes a simple 4-pin interface: VCC, GND, AO (Analog Output), DO (Digital Output).
• Commonly used in homes, factories, kitchens, gas storage areas for LPG leak detection.
• Also integrated into safety alarms, IoT projects, and industrial monitoring systems.
• Recommended to use in ventilated spaces to prevent sensor saturation or long-term degradation.
