Vibration measurement sensor for mysensors node

[Redguy]

I am looking for a way to monitor shocks and vibrations using a mysensors node.

There are plenty of vibration sensors et, but they just signal that a certain threshhold was reached or not.

what i want to do is monitor shocks and trembling throughout my apartment building caused by either external causes (passing train, earth shocks) or through the building itself (weather, other tenants, the elevators, thermal expansion of the concrete)

but i am not sure what type of sensor i should use.. any thoughts ?

@Redguy mayve @Cliff-Karlsson has some news on his eperiment: https://forum.mysensors.org/topic/5398/using-gyros-with-mysensors

Not sure if AWI's orientation sensor is sensitive enough, but I think it is possible to turn upp the gain. https://www.mysensors.org/build/orientation_actuator

Hello, you have to look for accelerometers.
Something very sensible I suppose for your use case.

Thanx guys !

I ordered a ADXL345 digital three-axis acceleration of gravity tilt module on ali to see what this will do with such small measurements.

stumbled upon this via one of Wallyllama's links :

Seems easy enough to have some fun with as well.
