MH-Z1341B-CH4 NDIR Infrared Methane (CH4) Gas Sensor for HVAC & Building Safety Equipment Civil Flammable Gas Detectors
Features:
Professional NDIR Infrared Principle: Adopts non-dispersive infrared detection technology, free from catalyst poisoning risks compared with traditional catalytic combustion sensors, ensuring long-term stable detection performance.
Ultra-low Power Consumption: Optimized internal circuit and optical structure design greatly reduces operating current, suitable for battery-powered portable devices and long-term standby household alarm equipment.
Excellent Environmental Adaptability: Built-in temperature and humidity compensation function achieves accurate and linear output under complex temperature and humidity conditions; composite film air chamber realizes waterproof and anti-corrosion performance.
Strong Anti-interference Ability: Effectively resists interference from water vapor, ethanol, acetic acid and other common interfering gases, avoiding false alarms and improving detection accuracy and reliability.
Long Service Life & High Stability: Features outstanding long-term operational stability, no aging failure of catalytic components, with a service life up to 10 years in standard application environments.
Simple Integration & Friendly Interface: Provides standard TTL UART digital signal output, compatible with mainstream single-chip microcomputers, requiring no complex peripheral circuits for rapid equipment integration.
Applications:
Household Gas Safety Monitoring: Specially designed for household natural gas and methane leakage alarm devices, providing real-time concentration monitoring and safety early warning for residential indoor gas environments.
HVAC & Building Safety Equipment: Integrated into heating, ventilation and air conditioning systems and building safety monitoring equipment for real-time flammable gas concentration detection and risk prevention.
Civil Flammable Gas Detectors: Serves as the core sensing element for portable and fixed civil methane detectors, supporting daily household gas safety inspection and leakage troubleshooting.
Smart Home Security System: Applied to smart home gas monitoring terminals and intelligent safety alarm systems to realize automatic monitoring and linkage early warning of gas leakage risks.
Light Industrial Environmental Monitoring: Suitable for low-concentration methane monitoring in small factories, storage rooms and confined civil spaces to eliminate hidden safety hazards of flammable gas accumulation.
