Easy way to use the 1-wire sensors like temperature, voltage and more.
OWFS -- 1-Wire file system. Use the Dallas 1-Wire and iButton chips with standard filesystem commands. Create temperature loggers. Monitor everything. OWHTTPD -- same system, only used as a light weight web server. OWFS is also ported to embedded routers, Mac OSX and Windows. Basically you can use these inexpensive little sensors and other chips with very simple wiring to sense and control the physical environment. The interface is very flexible -- everything from a web browser, to read and writing directly to the chip's "file" to integrating with your programs -- even over the internet. There is a growing number of 1-wire sensors: temperature, voltage, humidity, light, ultraviolet, pressure, thermisters, thermocouples, programmable microcontrollers, relays, lights, LCD panels, etc.
Python GUI program to work with Geiger counters like GMC-300/320/500
GeigerLog is a Python based GUI program to work with GQ Electronic's GMC-300 / 320 and now also GMC-500 Geiger counters. Available as "scripts" to run where a proper Python environment exists, or as "bundle", which brings its own Python environment (but currently runs on Linux only). GeigerLog allows reading of Geiger counter data, logging to file, printing to screen and plotting as graph, showing Count Rate vs. Time, both in various, selectable units. The history stored on the Geiger counter's internal memory can be extracted, analyzed and graphed in the same way. The graph is live auto-updated and allows various customization. Time ranges for analysis can be set manually or per left/right mouse click. GeigerLog can control some functions of a connected counter (limited to GMC-3xx counters!). Advanced analysis of the data now permits count rate histograms with Poisson fit for quality control of data, and FFT analysis for any periodic signal hidden within the data.
