USB-RAD121 Geiger Counter Overview ▼

The USB-RAD121 is a radiation detector that runs completely off your computer's USB port. The device features a classic geiger counter click and light pulse for every count registered, while radiation levels are displayed on the computer. The simple RadGraph software interface displays and graphs readings over time, and even allows the readings to be streamed to a personal webpage.

Make sure your home or office is safe from radiation by monitoring it with the USB-RAD121 geiger counter!

Code Examples ▼

Yes, we even provide you with a C++ code example and class for reading the USB-RAD121 geiger counter! The class allows you to connect to the device, take readings, convert your readings to mR/hr, and enable/disable the sound on the device. The library provided runs on Windows, but it is possible to get the code to run on MacOS X or Linux as well.

#include <time.h>
#include "CUSB_RAD121.h"

void main()
{
    CUSB_RAD121 counter;
    double cpm, mR_hr;

    counter.Open();                                 // Connect to the device
    Sleep( 30000 );                                 // Give the unit 30 seconds to gather counts
    counter.GetReading( &cpm );                     // Get the counts per minute from the device
    mR_hr = CUSB_RAD121::Calculate_mRhr( cpm );     // Convert cpm to mR/hr
    counter.Close();                                // Disconnect from the device
}
