From the README

OSpRad An open-source, low-cost, high-sensitivity spectroradiometer Developed by Jolyon Troscianko - 2022 Released under GPL-3.0 license. This project allows users to build their own low-cost, high-sensitivity spectroradiometer for measuring radiance/irradiance based on the Hamamatsu C12880MA chip. The spectral range of ~310 to 880nm and resoltuion of ~9nm make the OSpRad particularly well suited to visual modelling. Testing shows that the system can measure spectral radiance down to around 0.001 cd/sqm, and irradiance down to around 0.005 lx. Included in this project are the 3D STL files for…

About

Open hardware spectroradiometer built around a Hamamatsu C12880MA mini-spectrometer, a 3D-printed light-tight housing, and a Raspberry Pi or Arduino back-end. Designed by Jolyon Troscianko (Univ. Exeter) for sensory-ecology field work — measuring radiance and irradiance under natural lighting. Replaces the cardboard Public Lab Spectrometer with a full radiometric instrument and an actual hostable 3D model.
