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.

Abstract: The present invention relates to a gas sensor comprising a sensor layer (100) comprising a plasmonic sensor (102) provided so as to allow, upon illumination with electromagnetic radiation a localized surface plasmon resonance condition, a sensing layer (106) comprising a gas permeable material that, when exposed to a gas, modifies the localized surface plasmon resonance condition, a separating layer (104) arranged in between the sensor layer (100) and the sensing layer (106) such that the plasmonic sensor (102) is separated from the sensing layer (106). A gas sensing system and a method for sensing a presence of a gas is further disclosed.
