Design And Implementation Of The Driver System For A Hamamatsu C12880ma Microspectrometer

Recent miniaturization developments in devices for spectroscopy have reduced greatly their costs and increased their availability for a wide range of users and applications. This paper presents the design and implementation of a driver system for a Hamamatsu C12880MA microspectrometer. The system implementation was carried out and compared using two independent microcontroller modules: Arduino Uno and STM32F411RE Nucleo. We assessed the microspectrometer system parameters like resolution and integration time, as influenced by the choice of a driver microcontroller. We present a possible application of this microspectrometer system for measurements of ground coffee beans reflectance for control of coffee roasting.
