The MQ-8 gas sensor uses tin dioxide (SnO2) as the sensitive material, which exhibits low conductivity in clean air. When exposed to combustible gases, the sensor’s conductivity increases in proportion to the concentration of gas in the air. This change in conductivity can be easily converted into a corresponding output signal using a simple circuit. The MQ-8 is highly sensitive to hydrogen gas and can also effectively detect other hydrogen-containing gases. It is especially well-suited for detecting city gas, making it an affordable and versatile sensor for a wide range of applications.
Features:
- High Sensitivity: Excellent detection for hydrogen gas and other hydrogen-containing gases.
- Wide Detection Range: Detects a variety of combustible gases, particularly city gas.
- Low-Cost Solution: An affordable option for gas detection applications.
- Easy Integration: Simple circuit design for easy output signal conversion and system integration.
Applications:
- City Gas Detection: Ideal for detecting natural gas or other hydrogen-rich gases commonly found in urban areas.
- Home Gas Leak Detection: Used in domestic environments to detect leaks of combustible gases like hydrogen, methane, and propane.
- Industrial Safety Systems: Monitors hydrogen concentrations in industrial facilities to ensure safety and prevent accidents.
- Gas Sensor Systems: Integrated into gas detection and monitoring systems for real-time alerting in commercial and residential applications.
- Environmental Monitoring: Employed in environmental gas analysis for monitoring air quality in various settings.
