Stay on scale with the RS4D! Incorporating both velocity and acceleration sensors, the RS4D is an incredibly flexible seismograph. The multiple sensor technologies not only extends its usage applications, but also widens the range of motion it can detect. It is capable of measuring both strong motion and micro-seismic activity.
This highly portable, turnkey device integrates the velocity and acceleration sensors, digitizer, hyper-damper, and computer into a single unit. The difference between the RS1D and the RS4D is that the RS4D has three accelerometer sensors built into the board which detect ground motion both horizontally and vertically.
The addition of the accelerometer sensors effectively widens the decibel measurement band of this seismograph. This is interesting for people who live in active earthquake zones where the strong motion might be enough to “saturate” the geophone velocity sensor, or in other words exceed the instrument’s measurement limit. With the RS4D seismic activity should remain on scale and the combination of sensors also extends the device’s use cases, allowing it to be used in applications where an accelerometer is required, such as for structural health monitoring.
The RS4D is a well-rounded, strong motion seismograph. With multiple sensors, more data options, and a wider range it has a multitude of applications, including those that require an accelerometer.
All Raspberry Shake models are highly compatible, easily integrated into existing networks, and can be deployed rapidly. Find out what the experts are saying from multiple peer-reviewed articles about Raspberry Shakes.

Really enjoy the RS4D and tracking all the earthquakes here in Tokyo and Japan. The device is really easy to set up, only took about 10 minutes and does an amazing job at tracking everything from the diggers at a nearby construction site to the big earthquakes we get offshore in the Pacific. My station ID – AM.REC8D

I have been using the RS4D since October 2017. I absolutely love it. The setup is easy and support is always available from the group at RasbperryShake and the community of shakers. Living in Southern California, I knew there would be quakes to view. However, I never realized I could pick up large quakes from around the world. The RS4D’s sensitivity is amazing.
If you are interested in seeing what quakes recorded on my RS4D look like, here are some samples: https://www.youtube.com/channel/UCAhqlmltCW94ipicG8X-oLw

So i have been using this device RS4D for some years. My home in the Caribbean on one of the smaller islands. My home in Canada 🇨🇦.
The device is an outstanding value for money. At $1000 usd. It offers the security for your family. This company service and support is fantastic and one of the best.
I highly recommend this purchase.
