The C-GM Counter is a low cost (<50$) DIY Hardware & Firmware for building a Connected Geiger-Müller counter device to record beta-gamma radiation levels.

The counter is the hardware part of the overall A-GM project aimed for providing a long-term continuous measurement of the radioactivity level.
