Pleroma is a micro-spectrometer designed for Raspberry Pi applications. It is integrated with an optical MEMS chip and an image sensor.  The light to be measured is guided through its entrance port via an optical fiber and outputs the measured spectrum through the CSI port for data acquisition. Pleroma ensures accurate measurement with minimal noise. It includes evaluation software and Python source code that enable users to configure measurement settings, acquire and save data, and display graphs. Pleroma is designed to fully utilize the open-source capabilities of the Raspberry Pi Single Board Computer (SBC), allowing for easy and rapid customization of user applications.
