The kitchen is the source of household cooking fumes and a core line of defense for gas safety. Traditional gas sensors are often affected by moisture and cooking fumes, leading to false alarms, degradation, and frequent calibration, making them unsuitable for complex household environments. Tensensor's TX911-A household laser methane sensor, with its core TDLAS tunable laser absorption technology, redefines the accuracy, stability, and convenience of household gas detection, becoming an essential safety "sentinel" for modern families.

TX911-A Laser Methane Gas Sensor

    I. Core Technology as a Foundation: Precisely Detecting Only Methane

    TX911-A employs Tunable Laser Gas Absorption Spectroscopy (TDLAS) technology. Its through-beam structure precisely captures the characteristic absorption signal of methane molecules, detecting only methane and eliminating interference from other gases, thus preventing false alarms caused by alcohol, cooking fumes, and water vapor.

    High resolution up to 0.1% LEL, instant detection of minute leaks    

    Measurement error ±3% LEL at 25℃, stable and reliable data

    No oxygen required, accurate operation even in low-oxygen and confined spaces

    II. Moisture-resistant, poison-resistant, maintenance-free, 10-year long-term protection

    Traditional sensors are prone to poisoning, drift, and require annual calibration, while the TX911-A truly offers peace of mind:

    Resistant to moisture and poisoning, suitable for high-humidity kitchens, with no degradation even after long-term use

    Calibration-free design, install and use immediately, zero maintenance throughout

    Device lifespan >10 years, one-time deployment, ten years of peace of mind

    Compact size (76.5mm×21mm×14.1mm), weight <20g, space-saving embedded installation

    III. Ultra-fast response + stable output, early detection of danger

    Home safety, every second faster provides extra protection:

    Warm-up time only 15 seconds, quickly enters working state upon power-on

    T90 response <15 seconds, instantaneous response to leaks

    Standard UART Serial port (115200-8-1-N), actively uploads concentration, temperature, and status information every 4 seconds, compatible with smart gateways and alarm hosts, easily integrated into smart home systems.

    IV. Adaptable to Harsh Environments, Enhancing Home Safety

    The sensor is optimized for real-world home scenarios:

    Operating temperature: -10℃~50℃, Humidity: 0~95% RH (non-condensing)

    Wide voltage power supply: DC3.2~3.6V, low power consumption design: <300mA

    Supports temperature compensation and temperature control algorithms, ensuring stable output throughout the year

    Diffusion window ventilation design, enabling stable detection even in confined spaces.

    V. Wide Applicability, Whole-House Safety Coverage

    TX911-A is specifically designed for home gas leak detection, suitable for:

    Kitchen natural gas/LPG pipeline monitoring

    Enclosed spaces such as cabinets and gas meter boxes

    Gas system upgrades in older residential areas, and installation in newly renovated apartments

    Smart gas alarms, core modules for security systems

    VI. Why Choose the TX911-A? Compared to traditional semiconductor and catalytic combustion sensors, the TX911-A achieves three major breakthroughs:

    More accurate: Specifically identifies methane, with superior anti-interference capabilities, eliminating false alarms and missed alarms.

    More stable: Resistant to moisture and poisoning, maintains stable performance over long periods, and has a lifespan exceeding 10 years.

    More convenient: Calibration-free, easy to integrate, and compact, suitable for both home and mass production applications.

    Home safety is paramount, and there is zero tolerance for gas safety hazards. TX911-A home laser methane sensor, with its core technology of precise laser detection, brings professional-grade sensing technology to every household, safeguarding the warmth of every meal and the peace of every home. Whether it's new home renovation, old house upgrade, or smart security system upgrade, it is the preferred core component for home gas safety, providing tangible and lasting peace of mind.
