In various scenarios such as industrial monitoring, environmental sensing, and equipment integration, precise detection of oxygen concentration is a crucial prerequisite for safe operation and reliable data. Winpower Technology has been deeply engaged in the field of gas sensing and has meticulously developed the GSTB-400H V1.2 extreme current oxygen sensor module. With its comprehensive hard-core performance, flexible multi-interface compatibility, and wide environmental adaptability, it redefines the accuracy and efficiency of oxygen detection, becoming the preferred solution for gas sensing in various industries.
Unlike traditional oxygen sensing modules with single detection capabilities, GSTB-400H realizes simultaneous detection of oxygen concentration, temperature and humidity, and atmospheric pressure. It meets the multi-dimensional environmental data collection requirements in one step. Its oxygen concentration detection range covers 0.1% - 40% (customizable for other ranges), with an ultra-high resolution of 0.01% allowing for the detection of even subtle concentration changes. The accuracy of ±1% FS is stable and reliable within the -40 to +85°C temperature range. It is equipped with ±0.3°C temperature accuracy, ±3% RH humidity accuracy, and ±3 pa air pressure accuracy. Whether in harsh industrial environments or complex outdoor scenarios, the data output remains accurate and reliable.
Fast response and low waiting time are among the core advantages of GSTB-400H. The t90 response time of ≤ 15 seconds ensures that concentration detection does not require long waiting, allowing for real-time capture of environmental changes. The 60-second rapid preheating enables the module to enter the working state upon power-on, significantly improving detection efficiency. After 30 minutes of module operation, the readings stabilize, ensuring high data stability in long-term continuous monitoring, providing a solid foundation for continuous monitoring in various scenarios. What's more, in non-special pollution conditions, the module has a lifespan of ≥ 5 years, balancing high performance and long lifespan, significantly reducing the costs of later replacement and maintenance.
To meet the integration requirements of different devices and systems, GSTB-400H has designed a hardware design with flexible multi-interface configuration. It includes multiple sets of UART communication interfaces (3.3V), a dedicated power interface J3, a temperature and humidity pressure sensor interface J5, and an OLED screen interface J6. The spacing specifications are suitable for common wiring requirements, enabling seamless integration with various devices. The module uses 12V ± 0.5V DC wide voltage supply, with a normal room temperature power consumption of only 1.6 - 3.0W, and a transient power of ≤ 5W. The low power consumption design balances energy saving and equipment battery life. The diffusion air intake flow design, combined with water removal and 1 μm dust filtering sample gas requirements, is suitable for more practical applications.
In terms of environmental adaptability, GSTB-400H can be regarded as a "all-rounder". It operates within an ultra-wide temperature range of -40°C to +85°C, a full humidity range of 0 - 100% RH, and a working pressure range of 20 kpa to 130 kpa. It can easily handle extreme environments such as low temperature, high temperature, high humidity, and low pressure. With a running surface temperature of ≤ 150°C and a maximum temperature change rate of ±60°C/S, it can still work stably in scenarios with rapid temperature fluctuations. Meanwhile, the module adopts a standardized packaging size (W58.27mm x D42.11mm x H20.3mm), with a small size that does not occupy space, making it suitable for embedded integration and installation in various devices.
To ensure the stability and efficiency of data transmission, GSTB-400H is equipped with an exclusive UART communication protocol, with a baud rate of 9600bps, a start bit of 1, 8 data bits, and a stop bit of 1, without parity check. It supports data transmission in hexadecimal format, with the high byte first and the low byte last, ensuring clear and standardized data interaction. The module supports reading measurement results, software version numbers, firmware numbers, and various commands such as concentration calibration and standardization, with a minimum query cycle of 20ms, ensuring efficient and smooth data transmission. The sum verification mechanism effectively avoids data transmission errors and ensures the accurate reception of each group of data.
From the safety monitoring of industrial production lines, environmental perception in the field of environmental protection, to the supporting sensing of intelligent devices and precise detection in scientific research experiments, the GSTB-400H, with its precise detection performance, flexible adaptability, and stable operation, has become the core support for various industries' oxygen detection. Runpu Technology integrates multiple safety and protection designs in its design and production. The modules strictly prohibit the formation of condensate water and prohibit unauthorized disassembly. It is also equipped with detailed operating precautions to ensure the safety and lifespan of the equipment during use. At the same time, the module supports single-point concentration calibration. If drift occurs after long-term storage, it can be quickly calibrated to restore the precise detection capability.
