Popis: | A design, development and testing process for a cyber-physical system capable of versatile gas sensor measurement is described. Two approaches for the system are proposed; a stationary system for calibration and testing in laboratory environments and a portable system with wireless capability. The device utilizes a well-established Arduino microcontroller as well as a Raspberry Pi single board computer. The functionality is realized with C and Python programming languages. The operability is validated by system performance evaluation in the mixture of air and hydrogen gas, using both commercial and experimental Taguchi-type metal oxide semiconductor sensors. The experimental sensors are fabricated by inkjet printing platinum decorated tungsten oxide nanoparticles onto an electrode pattern on a silicon substrate which is then wire bonded to a chip carrier. The measurement platform demonstrated in our paper provides rapid prototyping capabilities for evaluating novel gas sensor materials in realistic measurement scenarios. |
