WIRELESS SENSOR MONITORING PILOT

Prepared September 8, 2026. For non-safety-critical monitoring planning.

INSTRUCTIONS
Define measurement and delivery requirements first. Count unique reports using
an explicit sensor/report identity. Separate missing, late, duplicate and buffered
records. Use real measurement time when available; label receipt-time-only data.

Owner / operator / period and timezone:
Quantity / unit / range / required accuracy / reference or calibration evidence:
Sensor IDs / locations / models / firmware:
Gateway and application models/versions/interfaces:
Sampling interval / reporting interval / aggregation behavior:
Maximum permitted data age and deadline definition:
Timestamp source / clock synchronization / uncertainty:
Expected reports and treatment of startup or planned downtime:
Unique received reports:
Unique received reports that missed the deadline:
Duplicates / out-of-order / buffered replay counts:
Longest gap and worst sensor:
Completeness = unique received / expected x 100:
Timely completeness = (unique received - late) / expected x 100:

FICTIONAL ARITHMETIC CHECK
3 sensors x 60 reports/hour x 24 hours = 4,320 expected.
4,276 unique received: completeness = 98.98% (rounded to two decimals).
40 of those received are late: 4,236 / 4,320 = 98.06% timely completeness.
These are teaching values and not acceptance thresholds.

FAILURE AND ALERT TESTS ON AN APPROVED BENCH
Sensor reporting interruption / quality flag / data age / alert:
Gateway or Ethernet interruption / stored readings / application behavior:
Recovery time / original measurement timestamps preserved / duplicate handling:
Harmless test alert / recipient / acknowledgement / action:

POWER AND MAINTENANCE
Usable battery capacity (mAh), source and conditions:
Measured whole-device average current (mA) and workload:
Idealized hours = mAh / mA; days = hours / 24:
Fictional check: 2,000 mAh / 0.20 mA = 10,000 hours = about 417 days.
Temperature, aging, self-discharge, voltage limits and maintenance margin:
Battery / calibration / firmware / retention / alert owners:
Acceptance decision / exceptions / action owner / next trigger:
NIST AMS 300-4, linked in the companion guide, provides deployment context.
