Introduction
This post is a rather disorganised list of different spectral sensors built on the Arduino platform. There is a corresponding list of commercial handheld spectral sensors.
DIY UV-VIS spectrometer
Journal of Chemical Education published an article - Teaching UV–Vis Spectroscopy with a 3D-Printable Smartphone Spectrophotometer, on a DIY spectrometer in 2018.

DIY AMS spectrometer
The 6-channel AMS arduino modules where introduced in the very first post of this blog. The core of these modules (or breakout boards) are one of the three versions of the AMS spectral sensor.
In this post I have just saved a link to a page explaining how to use the spectral sensor components and build your own spectrometer from scratch. As I am interested in other light sources then those available on the pre-fabricated modules, the design and Printed Circuit Board (PCB) layout introduced in the post on Let’s Build a Spectrometer is very useful.
DIY plasma glucose spectrophotometer
In 2018 the journal Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, published an article on Development of mini-spectrophotometer for determination of plasma glucose.
DIY Water dissolved phosphate colorimeter
In 2019 the journal Analytica Chimica Acta published an article on Development of a portable setup using a miniaturized and high precision colorimeter for the estimation of phosphate in natural water.
DIY Hamamatsu spectrometer C12666MA
The 256-channel Hamamatsu spectral sensor C12666MA is an alternative to the C1288MA sensor for a more advanced handheld spectrometer.
This version of Hamamatsu’s series of miniature spectrometers, were tested and evaluated in a 2016 article on Ultra-portable, wireless smartphone spectrometer for rapid, non-destructive testing of fruit ripeness(https://doi.org/10.1038/srep32504).
DIY Hamamatsu spectrometer C12880MA
The 288-channel Hamamatsu spectral sensor has been identified as a suitable candidate for a more advanced handheld spectrometer. The sensor is offered as an Arduino ready module by several producers.
In April 2020, the scientific journal HardwareX published an article (Portable low-cost open-source wireless spectrophotometer for fast and reliable measurements) (https://doi.org/10.1016/j.ohx.2020.e00108) on both how to build a handheld spectrometer using the Hamamatsu C12880MA spectral sensor, and also evaluated its performance. The article is open source, and code, .stl (3D print files) and sketches are available online at https://doi.org/10.17605/OSF.IO/RBFSE..
Low-cost setup developed for C12880MA micro-spectrometer. The system details revleas that it is setup is for Adafruit Fruit and also operatinal with other microcontrollers. The microcontroller interfaces directly with the Hamamatsu spectral sensor.
