Abstract: The present invention relates to a sensor device (100, 101, 102, 103) for sensing physiological information of a subject. To efficiently avoid or reduce ambient interference, the sensor device comprises a communication unit (7) for receiving, from an external source, context information indicating one or more of a modulation mode, settings of an interference reduction algorithm, and spectral information indicating an ambient light spectrum, said spectral information allowing the sensor device to determine the modulation mode and/or settings of an interference reduction algorithm, one or more light emitters (1, 2) for emitting modulated light onto the tissue of the subject, and a light detector (4) for detecting light which is transmitted through the tissue or/and which is reflected from the tissue.
