PLEASE NOTE THIS APP REQUIRES A GEIGER COUNTERGeiger Bot is a simple companion app for older analog-only Geiger counters. Using your device's microphone, it turns the Geiger counter's clicks or beeps into a count per minute (CPM) reading. This allows you to get a relative numeric reading with older Geiger counters. Normal background levels are usually 30-60 CPM.CPM can be used as a relative gauge to compare levels of radioactivity. The longer the app runs, the more accurate the reading. This is best used for comparing low-level radiation sources to background radiation-- for example, bananas.Obviously, for best results, the Geiger counter's speaker and the iOS device's microphone should be in as close proximity as possible, preferably in a quiet environment.The app has two main operating modes; default, and pulse. In the default operating mode, the CPM is calculated from the total counts observed and the elapsed time running. Pulse mode is switchable between 5 and 15 second intervals, and computes the CPM from only the last 5 or 15 seconds, respectively. This is more suitable for changing levels of radioactivity, but is less accurate. There is also a "zero" button to reset all counters.There are fundamental limitations in both the microphone input and speaker output of accurately capturing CPM. Even under the best circumstances, the speaker will tend to max out at about 400 CPM, which may be a gross understatement of the level of radioactivity being emitted. There is some error with normal readings, but it should be more accurate than manually counting the clicks with a stopwatch.It has been tested with a Kvarts DRSB-01 and an iPad. Please let me know if you have difficulty with a specific Geiger counter or iOS device combination.CPM can be used as a relative gauge to compare levels of radioactivity.
