#3d earthquake detection app install
These base isolation pendulums should be able to slide up-to 125 mm in each direction, so I also plan to install some sensors to measure those. Our houses are going to be taken down and rebuilt (the whole street) and the new built houses will have base isolation to prevent new damages after light quakes. So I wonder if these sensors can also detect the quite different quakes we have here, which are “surface quakes”. (on top of the 10’s of thousands of reports which have not yet been handles)
We had recently another one of about 3.4 on the Richter scale which resulted in about 4000 – 5000 damage reports of houses that got damaged. So from about 1.5 on the Richter scale a human can feel them here. The quakes here are induced by the decades of gas pumped out of the ground and their origin is at 3 km depth. I live in Groningen, in the Netherlands and we have lots of (small) earth quakes.īut as with all earth quakes, there is a relation between the number of small quakes and the number of stronger ones.įor example every 1000 quakes with up-to 1 on the Richter scale will give 100 up-to 2 on the Richter scale and 10 up-to 3 and so on… Posted in News Tagged earthquake, rohm Post navigation Of interest, the ancient Romans may have had a way to deflect earthquakes, so they probably didn’t care as much about detecting them.
#3d earthquake detection app how to
Rohm plans to have “OEM quantities” for sale next month which we hope means we can get smaller quantities from distributors.Ī lot of people spend a lot of time thinking about how to predict earthquakes, as we’ve seen before. That project used a Geophone as the detector, which could be replaced by this chip. Imagine a large sensor network sending back real-time data as an earthquake happens - something we saw last year using Raspberry Pi. We aren’t sure why we want to detect an earthquake, but we think we do.
Rohm suggests you could power the BP3901 for about 5 years with two AA batteries with the example of averaging 10 three-minute wake up events a month. That’s because the BP3901 is based on the combination of an accelerometer and a microcontroller in one package to detect movement, characterize it based on an algorithm and reacting through an I2C bus and an INT pin. In addition, while most sensors must be mounted completely flat, the BP3901 has a compensation method for angle which lets you mount it as much as 15 degrees rotated in either direction and still get good results. First, it supposedly eliminates false detections due to things like a heavy truck rumbling by.
The Rohm BP3901 has two primary features. Now, however, you can filter out errant vibrations and reliably detect earthquakes on a chip. In reality, though, a lot of things can shake a sensitive instrument that is detecting shaking, so - for example - mechanical sensors will produce a lot of false positives. If things are shaking, there’s an earthquake. If you’ve ever been in an earthquake you’d assume it would be pretty easy to detect one.
