The SENSE project is a Horizon 2020 Coordination and Support Action aiming to coordinate research and development efforts in academia and industry in low light-level sensoring. In addition, SENSE aims to transfer knowledge by initiating information and training events and material, for sharing the status of existing LLL sensors and providing information by outreach experiments and activities. This contribution focuses on developments,characteristics and existing calibration setups within the SENSE partner institutions for photo-sensing technologies like Silicon Photomultiplier (SiPM).
A short summary of the SENSE roadmap for the development of low light-level sensors will be given. In addition, a specific example of application of SiPMs in the field of astroparticle physics experiments will be discussed in more details, namely the scintillation detector readout for the surface detector enhancement of the IceCube observatory.
