Overview
Square Impact measures impacts, vibration and tilt on three axes and analyses them on the device. It tells you how hard something was hit and from which direction, whether it has tilted, and how the vibration is spread across frequencies: the fingerprint that reveals a worn bearing or a loose mounting. It reports on a schedule, on an impact, or when that fingerprint changes noticeably, so you get the signal rather than a stream of raw data.
Typical uses are vibration-based preventive maintenance on machinery, stability alerts on warehouse racking, tilt and stress on beams, and handling and shock analysis in transit. A temperature sensor and Wi-Fi geopositioning are built in. IP68 and IK06, a 4,000 mAh battery for over ten years, mounted with the included screw frame, adhesive or cable ties. Downloadable VSM apps add new analyses later.

Key features
- ✓Analysis on the device: Peak velocity, direction, tilt and a vibration spectrum are computed on board and sent as a few bytes instead of raw data streams.
- ✓Knows when something changed: Energy-change detection reports when the vibration profile shifts, not on every sample.
- ✓Racking, beams, machines: Stability alerts, tilt and stress monitoring, vibration-based preventive maintenance.
- ✓Built for the plant floor: IP68, IK06, ten-year battery; screw frame included, adhesive or cable-tie mounting too.
