The kitchen is the source of household cooking fumes and a core line of defense for gas safety. Traditional gas alarms often suffer from drawbacks such as cumbersome wiring, high power consumption, false alarms, short lifespan, and frequent maintenance, deterring many families. Tensensor's TX711-A70 combustible gas sensor, with its triple advantages of NDIR infrared principle, ultra-low power consumption, and long lifespan, brings a more stable, economical, and worry-free new solution for home gas detection, making it the ideal choice for modern family safety.

TX711-A70 Ultra-Low Power Home Methane Sensor

    I. Robust Technology Underpins Precise Adaptation for Home Use

    TX711-A70 employs non-dispersive infrared (NDIR) detection, a physical detection method that is oxygen-free, non-toxic, and does not suffer from degradation. It fundamentally overcomes the shortcomings of traditional electrochemical/semiconductor sensors, making it more suitable for complex and variable home environments.

    Key Highlights, Addressing Home Pain Points

    Extremely Low Power Consumption, Long-Lasting Battery Power

    With a 3.3V power supply, the average current for clean air is <50μA, with a peak of only 40mA@5V. In active upload mode, power consumption is as low as microamps during low-concentration periods, perfectly supporting battery-powered/low-power devices. No wiring required, easy installation, and easy adaptation to older neighborhoods and newly renovated kitchens.

    Ten-Year Lifespan, One-Time Investment for Long-Term Protection

    Designed for a lifespan of >10 years, far exceeding the 2-5 year lifespan of conventional home sensors, significantly reducing replacement costs and maintenance frequency. One installation provides ten years of peace of mind.

    Strong anti-interference, no false alarms or missed alarms

    The gas chamber composite membrane is waterproof and corrosion-resistant, resistant to water vapor, ethanol, and acetic acid interference. Kitchen fumes, steam, and alcohol spray do not affect the judgment. Combined with temperature and humidity compensation and excellent linear output, the detection is more accurate and stable.

    Digital serial port output, simpler connection

    Direct UART (TTL) serial port output, 3.0V level compatible with 5V systems, 9600 baud rate standard protocol, supports active upload/question and answer switching, quick connection to microcontrollers, smart gateways, and alarm motherboards, extremely low development threshold.

    Wide temperature and humidity range, fully compatible with home environments

    Operating temperature -10℃~60℃, humidity 0~95% RH non-condensing, stable operation in the cold winter of the north, the rainy season of the south, and the high temperature and humidity of the kitchen, unaffected by sudden environmental changes.

    II. Value in Home Use: Safety, Convenience, and Low Cost

    1. Zero Installation Threshold, Suitable for Both Old and New Homes

    DC 3.3~5.5V wide voltage range, microamp-level power consumption, compatible with battery/low-voltage power supply. No wiring or pre-installed sockets required; simply mount and use. Concealed installation does not disrupt the aesthetics of your home.

    2. More Reliable Protection, Peace of Mind for the Elderly and Children

    Stable operation after 180s preheating; T90 response time <30s, providing immediate leak warnings.

    High selectivity, only detects combustible gases; kitchen fumes and detergent evaporation will not trigger false alarms, minimizing disruption to daily life and anxiety.

    Built-in temperature compensation ensures accurate data and clearly readable concentration values, providing a clear overview of safety status.

    3. More Cost-Effective Throughout the Lifecycle

    Ultra-low power consumption = energy saving/battery saving;

Ten-year lifespan = fewer sensor replacements and less manual maintenance;

    High stability and low failure rate = reduced after-sales and replacement costs.

    One choice, long-term cost reduction, maximizing value.

    Home safety is paramount; gas alarms rely on sensors. TX711-A70 combustible gas sensor brings industrial-grade NDIR infrared technology to the home, addressing many pain points of traditional products with ultra-low power consumption, ultra-long lifespan, and ultra-high stability. It provides a high-performance, low-cost, and easily integrated core sensing solution for home gas alarms and HVAC safety systems, using technology to protect every home's cooking, making safety simpler and longer-lasting.
