#W-GM Counter by AdNovea (c)2018
W-GM Counter is a very low cost DIY Wifi Geiger-Müller counter (radioactivity).
The overall A-GM project is aimed for providing a long-term continuous measurement of the radioactivity level. It is made of an open-source Web application running on a SOHO server (e.g. QNAP sells Small Office Home Office servers) connected to a W-GM Counter device, C-GM Counter device or a compatible GMC-320 Geiger-Muller Counters from GQ Electronics LLC. Other compatible or DIY Geiger-Muller counters could also be used. This project has been developed and is provided AS IS by AdNovea®.
