Raspberry Shake 4D is a vibration monitoring system based on the Raspberry Pi that can monitor footsteps or earthquakes hundreds of miles away. In fact, at the beginning of 16th, the Raspberry Pi had a similar product Raspberry Shake, and Raspberry Shake 4D was an important upgrade. It added 4 vibration sensors, and the sensitivity was greatly improved. The vibration data obtained was before This means that it can not only detect earthquakes, but even the sound of washing machines in your home can be captured.
Raspberry Pi based miniature earthquake monitor: able to monitor earthquakes within 400 km
[China Instrument Network Instrument Development] If you live in a dangerous earthquake-prone area, a sensitive seismic monitoring and early warning system will be of great use. The Raspberry Pi card computer, since its inception, has been sought after by numerous computer enthusiasts and founders. Today, the Raspberry Pi engineers combined with the domestic geological environment, and released a new work - Raspberry Shake 4D seismic monitor.
In addition to monitoring vibrations, Raspberry Shake 4D can also locate vibration sites. So you just need to sit in the office or at home and connect your mobile phone to your device, and you will be able to observe more than magnitude 2 earthquakes within 80 kilometers radius of the APP. Earthquakes above Class 4 within 400 kilometers radius!
Like its name, 4D stands for 4 sensors, combined with a geophone from the original Raspberry Shake, plus 3 powerful MEMs accelerometers to provide the device with four recording channels.
The Raspberry Shake 4D board has also been redesigned to incorporate an additional 24-bit data processor that samples at the rate of 100 motion samples per second (double the former) and the data transfer rate also goes from one packet per second. Up to four, according to this accuracy, everyone can become a geologist in the future, and maybe even more than some "experts"
Due to the large impact of Raspberry Shake's early days, it also attracted the attention of government agencies such as geophysical and seismic monitoring agencies. They also started using Raspberry Shake 4D to quickly monitor the occurrence of earthquakes.
