The present invention relates to a sensor for sensing ambient conditions within a photosensitive media cartridge or at least in an environment surrounding the media or material in the cartridge. The present invention further relates to an imaging arrangement in which imaging of photosensitive material within an imaging device is controlled based on the sensed ambient conditions. A photosensitive media cartridge includes an ambient condition sensor mounted in the cartridge for sensing ambient conditions in the cartridge. When the cartridge is positioned at a media transfer position on an image-forming device that permits the conveyance of media from the cartridge to the image-forming device, image development or printing on the media in the image-forming device is controlled based on the sensed ambient conditions in the cartridge. The ambient condition sensor includes a cover layer and a conductive layer, wherein a rate of response to ambient conditions of the cover layer matches rate of response to ambient conditions of the photosensitive media to be developed. As a further option, the media itself can include a conductive layer so that the media can be the sensor.
