Spectral signature is a characteristic property of a material that represent how the matter interacts with an electromagnetic radiation at different wavelengths. By looking at the reflectance spectra of a material, scientists can not only retrieve¬†vital¬†information like the¬†chemical composition and¬†crystal structure of the material, but also the presence of any impurities or third¬†element within it. The instrument used to derive such spectra is called Spectrometer. While a commercial spectrometer could cost a huge amount of money, Akshat Wahi‚Äės work is intended to make an open-source tool¬†called¬†WiSci to allow¬†spectroscopy accessible to everyone.

WiSc is a portable spectrometer that communicates to an Android device over Bluetooth to store and visualize the spectral data. It uses Hamamatsu’s C12666MA mini-spectrometer at the front end to collect spectral signature from a target in wavelengths ranging from 340 to 780 nm. The hardware setup includes an Arduino board to read measurements from C12666MA and a HC-05 Bluetooth module for sending the data to the Android device. The android application was developed using Android Studio IDE and is compatible with Android 2.3.3 or higher.
