ABH-300-SH
Shock & tilt tracker
Handling evidence
Adds accelerometer shock and tilt channels to the industrial monitor — evidence for how sensitive cargo was handled, not just how it was kept.

ABH-300-SH — every number a QA team asks for
Channel-level accuracy, memory depth in readings, enclosure geometry and the firmware trust chain — the full picture before you ask for the pilot.

The ABH line is at the design-frozen, pre-production stage: every enclosure has passed generated fit-check geometry (791/791 checks, 20/20 SKUs) and every battery-life, drop, thermal and IP figure shown is a calculated or simulated design estimate — measured values replace them as validation hardware runs. Regulatory marks above are the certification roadmap, not held certificates.
- Shock events carry timestamps and magnitudes into the same audit chain
- Combine with ABH-100-G trackers for in-transit condition + handling evidence
- Tilt channel for laying-sensitive equipment and cryogenic dewars
- Shock & tilt-sensitive cargoAccelerometer channel adds shock/tilt evidence to the environmental record.

One PCB, one firmware, one compliant record
One 80 × 50 mm 4-layer platform PCB — 146 parts, single-sided SMT — becomes 20 SKUs by BOM selection and a SKU record in the on-board ID EEPROM.

Plug an offline logger into a PC and it enumerates a FAT16 drive with README.TXT, DATA.CSV and an ECDSA P-256-signed REPORT.PDF — a self-verifying trip record.
Probe channel templates live in the ID EEPROM; the platform tracks NIST-traceable calibration certificates, due dates and reminders per probe.
