MQ-9 Carbon Monoxide Combustible Gas Sensor Module

The MQ-9 Carbon Monoxide Combustible Gas Sensor Module is a highly sensitive and selective device designed to detect and measure both carbon monoxide (CO) and combustible gases in the surrounding environment. It utilizes a semiconductor oxide sensing element to detect these gases, providing a reliable and accurate output signal.

Key Features:

• Dual Gas Detection: Detects both carbon monoxide and combustible gases (such as methane, propane, and butane).
• High Sensitivity: Offers accurate detection of even low concentrations of gases.
• Analog Output: Provides an analog voltage output proportional to the concentration of the detected gas.
• Temperature Compensation: Automatically compensates for temperature variations to ensure accurate measurements.
• Compact Size: Small and lightweight for easy integration into various applications.

Applications:

• Carbon Monoxide and Combustible Gas Detection: Detects and alerts users to potential hazards from both CO and combustible gases.
• Home Safety: Monitors CO and combustible gas levels in homes and other indoor spaces.
• Industrial Process Control: Regulates CO and combustible gas emissions in industrial processes.
• Scientific Research: Studies CO and combustible gas behavior and emissions.
• Environmental Monitoring: Monitors CO and combustible gas levels in the atmosphere.
