Resistance fluctuations observed as voltage fluctuations across resistance gas sensors can increase the sensibility and selectivity of gas sensing. This conclusion leads to the question how to prepare in practice a cheap measurement system for gas detection when resistance gas sensors of various resistance are applied. Therefore it is valuable to consider different noise measurement systems that would apply fluctuation-enhanced gas sensing. This study presents two solutions of noise systems that can be used for noise measurements in Taguchi gas sensors currently available on the market and the prototype monosized nanoparticle gas sensors having much greater DC resistance than the sensors currently on sale.
