Abstract
We present a cellphone camera-based spectrometer for measure of phosphorus and nitrogen concentration. The combined hardware/software is designed to meet the following goals: require only 3D printed parts and cheap, readily available materials, such that it can be affordable/fabricable in many makerspace/fablabs; be transparent and user friendly, such as to function as teaching tool in K-12 water-related lesson plans and in parks; produce accurate results vs. comparable Hach colorimeters; and allow simple aggregation of resulting data, which is shared with the users.
The intent is to provide a much needed supplementary data set for nutrient loading from local sources along the watershed, by local inhabitants, while promoting a tangible appreciation of water-related issues in young people.
