Spectron - an open source project for measuring and obtaining digital devices spectral sensitivity curves. Initially this was conceived with the goal of constructing an automated device with an aid to accurately measure spectral sensitivity curves for digital camera sensors. The project has a broader use though and can be used to measure spectral sensitivity curves of various light sensitive sensors (not just camera sensors) - for example spectral sensitivity curves of photodiodes.
