Title
Temperature Compensation and Data Fusion Based on a Multifunctional Gas Detector
Abstract
The requirements for functionality and accuracy of gas detectors in modern society are getting higher and higher, and many gas sensors inherently have temperature sensitivity and cross sensitivity. The sensor information fusion technology for industrial applications is becoming increasingly important. A multifunctional hand-held gas detector has been designed based on an ultralow-power MCU MSP430, which can detect the concentration of O2, CO, CH4, and H2S. This design conducted the temperature compensation for a linear assumption of temperature effect, and clarified the methods for a nonlinear assumption. The experiments tested the cross sensitivity between the gas sensors, and verified that the instrument can effectively reduce the influence of cross sensitivity using the surface fitting algorithm and enhance the measurement accuracy by one to two orders of magnitude. Based on these conclusions, we can obtain that the instrument is stable and it meets the accuracy requirements well.
