Abstract
The development and test of a multi-wavelength setup for optical stimulation of gas sensors consisting of an LED driver board and a gas measurement chamber is presented. The aim of this work was to facilitate dynamic sensor measurements under variable light wavelength and intensity to investigate the potential of light stimulation for improved sensor performance, i.e. sensitivity and selectivity. The setup was tested on two different sensors in varying gas atmosphere to evaluate its performance.
