There was a problem that wiring is obstructive and difficult with wired accelerometers.
A wireless accelerometer (waterproof standard:IP68) makes it easier to install without worring about wiring.
Approximate standard size : φ40 X 51mm
(The connection with a separate battery box is needed.
Approximate standard size : 70 X 46 X 102 mm
It is possible to acquite X / Y / Z acceleration at the same time since it is a 3D acceleraion sensor.
A separate wireless access point is required since dB-2 does not have a wireless function.
