Thanks to miki_e who set up a PC with GMC-300 for remote access, we now have a (partial) support for GQ Electronics GMC-300 sensor.

The app is not finished yet but the basic functionality seems to be working, it reads the data and returns it to the server just like our USB app.

For now the app works only as anonymous platform with app_info.xml, so it requires some BOINC knowledge to set up.

If you have a GMC-300 and would like to test it with Radioactive@Home, take a look at this thread

The server does not have support for sensors with tubes other than SBM-20/STS-5 yet, it uses a fixed divider so the values returned from GMC-300 are underestimated when displayed on our map and graphs (this does not affect the raw data in the database, as it is stored as number of pulses and time). It's not that bad, as far as I can see the values are off by 15-20%.

This is going to be changed, but it requires a lot of work (the server has to guess the default tube type for a given sensor, the user should be able to override the setting).
