The Raspberry Jam Universal Digitizer (RJAM) is the latest addition to the Raspberry Shake product portfolio. A powerful universal digitizer compatible with most seismometers and infrasound sensors such as the Trillium Compact, S-13 or L-4C (for full details, supported sensors and technical specifications please see here).
We have had many inquiries over the years for a device that allows scientists and hobbyists to use their own sensors. Now you can with the RJAM, it is ideal for geophysical institutes and seismology hobbyists alike.
With the RJAM, you can add a variety of sensors from short-period to broadband seismometers and infrasound sensors. The RJAM can also be configured for passive or active sensors. This can be accomplished by changing some resistor values. To simplify the setup process for you, you can have us mount the resistors by selecting the customization desired from the drop down above..
The circuit board of the Raspberry Jam incorporates three 24 bit (144 dB) digitizers, each sampling the Earth’s motion at 100 samples per second. In addition, the digitizer has a data transmission rate of four packets per second, making it Earthquake Early Warning compatible. For full specifications please see here.
This product listing comes with the Raspberry Jam Universal Digitizer, Raspberry Pi computer and an all weather enclosure. The hardened enclosure, included here, will protect your unit against rainfall, dust and bugs. We call this an “IP67” enclosure, which means that it is fully weather proof, dust tight and can withstand immersion (30 minutes at 1 meter).
In an effort to bring you a more robust solution, the enclosure shown in the product photos above has been replaced by a larger enclosure (160 mm x 90 mm x 90 mm) and the plastic connections have been replaced with metal ones. New photos are coming soon!
