Both the Vernier Radiation Monitor (VRM-BTD) and Go Direct^® Radiation Monitor (GDX-RAD) can be used with LabVIEW.

Go Direct Radiation
Download and install the Go Direct Sensors package for your version of LabVIEW. The package includes the necessary drivers, example VIs, and Express VIs that will allow you to connect to and collect data from Go Direct Radiation.

Vernier Radiation Monitor with SensorDAQ interface
If you are using the Vernier Radiation Monitor with our SensorDAQ (SDAQ) interface, download and install the SensorDAQ Interface package. Among the example VIs are two Radiation Monitor examples.

Vernier Radiation Monitor with LabQuest interface
If you are using the Vernier Radiation Monitor with one of our LabQuest interfaces, such as the LabQuest 3 (LABQ3) or LabQuest Mini (LQ-MINI), download and install the LabQuest Interfaces package. Although we don’t have any example VIs already written for the Radiation Monitor, we do have a work-around though.
 
With the Vernier Radiation Monitor to a LabQuest interface, open the LQ Photogate Count VI (from the Vernier examples folder) in LabVIEW. The Photogate Count VI is a simple VI that lets you set the count interval (in seconds); it reads back the count for the previous interval, as well as the total count. Although the VI is written for a photogate, it works with the Radiation Monitor as is.
 
You’ll have to do some additional programming to store the counts for each interval, calculate the average counts per interval, and graph it all, but the basic functionality is there.
