Abstract
The present invention relates to a method and device for determining a property of an ambient environment. The device comprises a plasmonic sensing element; a first light source for illuminating a first and a second light sensor, the first sensor via the plasmonic sensing element; a second light source for illuminating the light sensors; circuitry for executing: a control function controlling light sources, a function receiving a measurement from the first sensor, and a first signal from the second sensor, a function receiving a reference from the first sensor, and a second signal from the second sensor, a function determining the property by comparing the measurement and reference signals, and the control function further controlling light sources such that a relation of intensities of light emitted by the light sources is constant over time.
