Open Gamma Detector Front Open Gamma Detector Back


Open hardware for a hackable gamma spectrometer all-in-one device using a popular NaI(Tl) scintillation crystal and a silicon photomultiplier (SiPM). Extremely affordable design for a powerful DIY gamma spectroscopy setup with a total parts cost of under around 200 USD.

The detector uses a standard serial-over-USB and hardware UART connections so that it can be integrated into as many other projects as possible, for example data logging with a Raspberry Pi, weather stations, Arduino projects, etc. It includes both scintillation counter and multichannel analyzer (MCA) functions depending on how you want to use it.
