Many areas of science rely on experiments that use spectral measurements for diagnostics and theoretical validation. Spectral measurements separate the photons captured by the detectors according to their energy. Each photon produces a pulse whose height is proportional to the photon energy. Nowadays, state-of-the-art spectrometers include analog-to-digital converters (ADC) that deliver more than a hundred million samples per second, and enough processing power to run an operational system. On the other hand, small lab projects can make use of cheap microcontroller units (MCU) for spectral measurements. The spectrum size and resolution will be limited by the ADC sampling rate and bit-precision, as well as electronic noise and the detector’s intrinsic resolution.
