Fig. 5: Signal robustness according to ISO 26412:2010 at different sensor operating temperatures in humid conditions in synthetic air.
From: Neural network enabled nanoplasmonic hydrogen sensors with 100 ppm limit of detection in humid air
a Illustration of the ISO 26412:2010 requirements on sensor signal robustness. The gray box denotes the ±30% tolerance from the signal obtained in 50% RH. To meet the ISO requirement, the sensor signal at other RH than 50% must fall within the gray-box. b Standard Δλpeak readout sensor signal robustness evaluation according to the ISO 26142:2010 standard for 0.13, 0.28, 0.6, and 1.3% H2 concentrations in humid synthetic air. c DDNN-based sensor signal robustness evaluation according to the ISO 26142:2010 standard for 0.06, 0.13, 0.28, 0.6, and 1.3% H2 concentrations in humid synthetic air.
