Summary:The invention relates to a sensing system for sensing a substance in a fluid. The sensing system comprises a sensing site (132) at which the substance is to be sensed and a reference site (131). A signal generation unit generates a sensing signal by sensing the sensing site (132) and a reference signal by sensing the reference site (131). The reference signal is used for normalizing the sensing signal, wherein the sensing site (132) and the reference site (131) are arranged such that a drift variation of the normalized sensing signal is within a noise variation of the normalized sensing signal. This improves the accuracy of the normalized sensing signal.
