I2c interface of Omron DS7

I just got 2 pcs of omrons seismic sensor DS7 see: D7S Vibration Sensor | OMRON - Americas

My plan is to connect it via i2c to an ESP32 to send seismic events via LoRa to my network in order to react on minimal seismic activities in the grounds below.

does anyone has an idea how to access data from the DS7? Datasheet doesn´t tell much.

Datasheet doesn't tell much.

Indeed.

If you do a Google search on "github d7s" several libraries show up for either using or reverse engineering.
This one in particular looks useful

Thank you so much!!!
