spectrometer craft
with Arduino & microbit


Spectrometry of light sources, lasers, environment

Radiometer: Measure irradiance of light sources, LEDs, lasers, sun, Internet of Things Sensor for Sunlight, public lightning

Spectrometer: measure reflected spectrum from four spectrally balanced lights being reflected from surfaces. IoT NDVI index, Normalized Difference Vegetation Index, whiteness of papers, walls, chemical and environmental agents, and more...

Spectrophotometer: measure light passing through a cuvette containing liquids of various colors. With spectrometric camera mode, you can even observe kinetics of reactions, measure adding of concentrates to beverages online, or measure turbidity and fluorescence of liquids, algae, phytoplankton.

Programmable: spectrometer, spectroradiometer with Arduino and microbit.


We design, create and re-create products to last through the harshest environments on earth and beyond. Reliable, portable, handcrafted. So you can concentrate on data, analysis and results. We created the first open source spectrometer with Arduino.

Spectruino THREE

Spectruino is the first open source, Arduino based spectrometer. Third generation is the lightest yet, built from Aluminum frame and EPDM light foam, it can withstand the extremes of Stratospheric missions, or the comfort of your home or robotic class. It measures sunlight, albedo, LEDs, lasers and has even been used for Raman spectrometer construction.

Technical Information

Lumini and Spectruino are Spectrometers to measure light intensity vs. wavelength. Internally, this is achieved through a combination of diffraction grating with linear CCD camera and custom firmware.

All technical specifications are preliminary and may change without further notice.
