In industrial production and special operating environments, gas leaks and abnormal concentrations pose potential safety hazards, making real-time and accurate gas monitoring crucial. Tensensor's TZHCO-01B four-in-one gas detection module integrates the detection of four key gases—CO, H₂S, O₂, and CH₄—providing a one-stop, intelligent solution for industrial safety monitoring with its high integration, compact size, fast response, and stable output.

TZHCO-01B gas sensor module

    1. All-in-One Design, Covering Four Key Gases in One Unit

    The TZHCO-01B simultaneously monitors carbon monoxide (CO), hydrogen sulfide (H₂S), oxygen (O₂), and methane (CH₄), covering common toxic, harmful, flammable, and oxygen-deficient risks. It is suitable for various scenarios such as factory workshops, underground operations, tunnel construction, and coal mine monitoring. The module uses a digital serial port (UART) to output concentration data in real time, supporting both active upload and query-response communication modes, facilitating integration into handheld devices, fixed installation systems, or personnel-worn devices.

    2. High Precision and High Stability, Adaptable to Complex Industrial Environments

    Wide Range Monitoring: CO (0-1000ppm), H₂S (0-100ppm), O₂ (0-30%VOL), CH₄ (0-100%LEL), with fine resolution meeting industrial-grade accuracy requirements.

    Rapid Response: ≤30-second response time, providing timely warnings and buying time for emergency response.

    Strong Environmental Adaptability: Operating temperature -20℃~50℃, humidity 15%~90%RH, built-in temperature compensation ensures reliable data.

    3. Intelligent Early Warning and Status Indication, Clear Human-Machine Interaction

    The module is equipped with dual-color indicator lights:

    Green flashing light: Module is powered on normally, and the operating status is visible.

    Red light graded alarm: Level 1 alarm (1 flash per second), Level 2 alarm (2 flashes per second), corresponding to different gas concentration thresholds, intuitively indicating the risk level.

    4. Plug and Play, Easy Integration and Maintenance

    Compact and Lightweight: Weighing <50g, compact size, easy to embed in various devices.

    Standard Interface: Provides VCC, GND, TX, RX, etc. pins, plug and play, supporting rapid system integration.

    Long Lifespan Design: Expected lifespan of 2 years, supports periodic calibration, low maintenance cost.

    5. Wide Range of Applications, Safeguarding Multiple Safety Levels

    Factory and Workshop: Real-time monitoring of combustible and toxic gas leaks, preventing explosions and poisoning accidents.

    Underground and Tunnel Operations: Detects oxygen deficiency and H₂S accumulation, ensuring respiratory safety for workers.

    Coal Mines and Energy Sites: Monitors CH₄ concentration to prevent gas outbursts and explosion risks.

    Environmental Protection and Emergency Detection: Handheld portable devices allow for rapid deployment, suitable for on-site inspections and emergency response.

    6.. Usage Recommendations and Maintenance Tips

    To maintain long-term accurate operation, it is recommended to:

    Perform calibration every six months to one year;

    Maintain a power supply ripple of less than 30mV;

    Avoid prolonged exposure to high concentrations of gases or extreme temperature and humidity environments;

    In environments with large wind speed variations or high humidity, it can be used in conjunction with an air pump or a waterproof and breathable device.

    The TZHCO-01B four-in-one gas detection module, with its advantages of multi-gas compatibility, high reliability, and easy integration, has become a "smart sentinel" in the field of industrial safety monitoring. Whether fixedly installed or portable, it can continuously provide accurate gas data, building a solid defense for personnel safety, equipment protection, and environmental health.
