In complex environments such as industrial production, underground operations, tunnel construction, and coal mine monitoring, the leakage and accumulation of hazardous gases pose significant threats to personnel safety and production stability. Achieving real-time, accurate, and reliable monitoring of multiple gases has become a core requirement for enterprise safety management. 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 solution for industrial gas safety monitoring through its highly integrated, intelligent, and easy-to-integrate design.

TZHCO-01B gas sensor module

Integrated Multi-Gas Monitoring, Comprehensive Coverage of Industrial Scenarios

    Traditional gas detection equipment often has limited functionality, requiring multiple devices to operate in conjunction, resulting in complex deployments and high costs. The TZHCO-01B innovatively integrates four common hazardous gas sensors (CO, H₂S, O₂, CH₄) into one unit, covering a wide range of risk scenarios from toxic gases to flammable gases, and from oxygen deficiency to excessive oxygen content. It is suitable for:

    Factory workshops: Monitoring leaks of flammable and toxic gases such as CO and CH₄;

    Underground and tunnel operations: Real-time detection of O₂ content and H₂S accumulation;

    Coal mine environments: CH₄ concentration monitoring and early warning;

    Chemical, petroleum, and gas industries: Comprehensive monitoring of environments with multiple gases coexisting.

High precision, fast response, and reliable real-time data

    The TZHCO-01B employs a highly stable electrochemical and catalytic combustion sensor, coupled with intelligent temperature compensation and signal processing circuitry, providing excellent anti-interference capabilities and long-term stability:

    Wide measurement range: CO (0-1000ppm), H₂S (0-100ppm), O₂ (0-30%VOL), CH₄ (0-100%LEL);

    High resolution: Supports accurate identification of 1ppm (CO/H₂S), 0.1%VOL (O₂), and 1%LEL (CH₄);

    Rapid response: Gas concentration changes are reported in less than 30 seconds;

    Dual-level alarm mechanism: Supports configurable first and second-level alarm thresholds, coupled with red and green dual-color indicator lights for tiered audible and visual warnings.

Digital output, flexible integration, supporting multiple application forms

    The module adopts UART serial port output, compatible with 3.5~5V power supply, and is compact (<50g), easily embedded in various devices:

    Portable devices: for handheld detectors, personal safety devices;

    Fixed systems: embedded in monitoring terminals, safety panels, and inspection robots;

    IoT platform: connects to the cloud via a microcontroller for remote real-time monitoring and data analysis.

    The communication protocol supports both active upload and query-response modes, allowing users to flexibly configure according to system needs, achieving low-power or real-time streaming data output.

Long-lasting and durable, adaptable to harsh industrial environments

    The product has excellent environmental adaptability:

    Operating temperature and humidity range: -20℃~50℃, 15%~90%RH (non-condensing);

    Protective design recommendations: supports the addition of accessories such as air pumps, waterproof and breathable membranes, and drying tubes, adapting to complex working conditions such as high and low temperatures, high humidity, dust, and unstable airflow;

    Expected lifespan: up to 2 years in normal air, with low maintenance costs.

    In today's world where industrial safety is increasingly valued, the TZHCO-01B four-in-one gas detection module, with its high integration, high reliability, strong compatibility, and flexible deployment, has become an ideal choice for gas safety monitoring in various industrial scenarios. It not only improves monitoring efficiency and response speed but also provides reliable technical support for enterprises to build intelligent and systematic safety protection systems.
