MQ-5 Liquefied Gas & Coal Gas Sensor Module

The MQ-5 Liquefied Gas & Coal Gas Sensor Module is a highly sensitive and selective device designed to detect and measure various combustible gases, including liquefied petroleum gas (LPG), propane, butane, and coal gas. It utilizes a semiconductor oxide sensing element to detect these gases, providing a reliable and accurate output signal.

Key Features:

• Multi-Gas Detection: Detects LPG, propane, butane, and coal gas.
• 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:

• Gas Leak Detection: Detects leaks of LPG, propane, butane, and coal gas.
• Home Safety: Monitors gas levels in homes and other indoor spaces.
• Industrial Process Control: Regulates gas emissions in industrial processes.
• Scientific Research: Studies gas behavior and emissions.
• Environmental Monitoring: Monitors gas levels in the atmosphere.
