Abstract:

To facilitate the data acquisition and analysis of hydrogen sensors in early stages, a set of data acquisition and processing systems for hydrogen sensors has been developed. The system applies the embedded technology and combines the acquisition terminal with the upper computer to realize the data acquisition and processing of hydrogen sensors. At present, it has been applied to a constant voltage type hydrogen sensor to collect and process data. The conversion from resistance to current to voltage is realized. The resistance value at both ends of the measured material is within 200 KΩ. The measurement accuracy is 1 Ω. The upper computer assists with the temperature compensation mechanism to achieve the effective data acquisition and processing of the measured materials. The practical application shows that the system is of great significance to the data acquisition and processing of early hydrogen sensors.
