The invention relates to a device and a method for detecting rain (4). The device for detecting rain comprises a camera with an image sensor (5) and colour filters for pixels of the image sensor in a number of primary filter colours (R; G; B) and an illumination source (3) for producing monochromatic light (h) of a first primary filter colour. The monochromatic light is provided in a visible wavelength range which is transmitted by the first primary filter colour and blocked by the other primary filter colours. The camera and the illumination source (3) are designed and arranged in such a manner that the camera can detect a signal from the monochromatic light (r1, r2′) with which the illumination source illuminates a pane (2).
