MQ-5 Methane LPG Liquid Propane Gas Sensor Module

MQ-5 Methane LPG Liquid Propane Gas Sensor Module:

The MQ-5 Gas Sensor Module is a reliable solution for detecting gas leaks in residential, commercial, and industrial environments. It is specifically designed to sense LPG, natural gas, and coal gas, while excluding interference from alcohol, cooking fumes, and cigarette smoke.

Overview:

At the core of the MQ-5 is SnO₂ (Tin Dioxide), a sensitive material with low conductivity in clean air. When exposed to combustible gases, its conductivity increases in proportion to the gas concentration. This change is translated into an output signal via a simple circuit, enabling accurate gas detection.

Key Features:

• High Sensitivity: Effectively detects LPG, methane, propane, and butane gases.
• Selective Detection: Minimal sensitivity to alcohol and smoke reduces false alarms.
• Adjustable Sensitivity: A built-in potentiometer allows fine-tuning to meet specific application requirements.
• Fast Response Time: Quickly detects gas leaks for prompt safety measures.
• Long Lifespan and Stability: Durable design ensures consistent performance with minimal maintenance.
• Simple Integration: Operates on a basic drive circuit, making it easy to incorporate into various systems.

Specifications:

• Operating Voltage: 5V DC
• Sensitivity Range: Detects methane, propane, butane, and other combustible gases.
• Output:
  • Analog Output (Aout): Proportional to gas concentration.
  • Digital Output (Dout): Triggered when the gas concentration exceeds a set threshold.
• Connections:
  • VCC:5V ~ 5.0V DC
  • GND: Ground
  • Aout: Analog signal to MCU/IO pin
  • Dout: Digital signal to MCU/IO pin

Applications:

• Safety Systems: Gas leak detection in homes, kitchens, or industrial facilities.
• Industrial Monitoring: Ensuring safe gas levels in processing plants.
• Consumer Electronics: Gas alarms and portable gas detection devices.

The MQ-5 Methane LPG Liquid Propane Gas Sensor Module offers a cost-effective, robust, and versatile solution for enhancing safety in gas monitoring applications. Its reliability and ease of use make it an essential component for detecting gas leaks and preventing potential hazards.
