MQ-9 Carbon Monoxide, Methane and LPG Gas Sensor Module

The MQ-9 Carbon Monoxide, Methane, and LPG Gas Sensor Module is designed to detect these gases with high sensitivity. It utilizes SnO2 as its sensitive material, which has lower conductivity in clean air. Here are the key features, specifications, and applications of the MQ-9 sensor module:

  Features:  

• High sensitivity to Carbon Monoxide (CO), Methane (CH4), and LPG
• Dual-panel design with power indicator and TTL signal output instructions
• Digital Output (DO) for TTL switch signal output
• Analog Output (AO) for analog signal output
• Low-level TTL output signal
• Analog output voltage increases with gas concentration
• Long life and stability, quick response, and resume
• Four screw holes for easy positioning

  Specifications:  

• Model: MQ-9
• Operating Voltage: 5V
• Current Consumption: 150mA
• Digital Output (DO): TTL 0 and 1 (0.1 and 5V)
• Analog Output (AO): 0.1-0.3V (Relative to Clean)
• Dimensions: 32mm x 20mm x 16mm
• Weight: 5g

  Applications:  

• Suitable for home or factory gas leakage monitoring devices
• Ideal for detecting Carbon Monoxide, Methane, LPG, and other combustible gases
• Widely used in domestic gas leakage detectors, industrial gas detectors, portable gas detectors, etc.

  Package Includes:  

• 1 x MQ-9 Carbon Monoxide, Methane, and LPG Gas Sensor Module

The MQ-9 sensor module provides a reliable and cost-effective solution for detecting Carbon Monoxide, Methane, and LPG gases, making it suitable for various gas detection applications in both residential and industrial environments.
