Data Logger Sample Rate Storage Days Calculator
Budget complete logger records after header overhead and distinguish N samples from N−1 observed elapsed intervals; no filesystem wear, compression or indefinite data retention assumption.
Description
Logger storage holds complete sample records after fixed overhead.
Logger storage holds complete sample records after fixed overhead. N samples span N−1 elapsed sampling intervals.
Budget complete logger records after header overhead and distinguish N samples from N−1 observed elapsed intervals; no filesystem wear, compression or indefinite data retention assumption.
When to use Data Logger Sample Rate Storage Days Calculator
Use this tool to budget complete logger records after header overhead and distinguish N samples from N−1 observed elapsed intervals; no filesystem wear, compression or indefinite data retention assumption.
Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
How to use Data Logger Sample Rate Storage Days Calculator and understand its results
- Prepare the collection, exposure, scheduling or financial records required for this calculation. Keep row order and the declared units consistent.
- Enter usableLoggerBytes, headerBytes, bytesPerSample, sampleIntervalSeconds using the field table and calculation rules, then run the tool.
- Read maximumCompleteStoredSamples, firstToLastStoredSampleSpanDays. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| usableLoggerBytes | Usable logger bytes | integer | Required |
| headerBytes | Header bytes | integer | Required |
| bytesPerSample | Bytes per sample | integer | Required |
| sampleIntervalSeconds | Sample interval seconds | number | Required |
Use nonnegative integer usable/header bytes with header no greater than usable, positive integer record bytes and positive interval seconds. Return complete samples and max(0,N−1) × interval/86400 days.1
samples = floor((usable bytes − header bytes)/bytes per sample) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| maximumCompleteStoredSamples | Maximum complete stored samples | number |
| firstToLastStoredSampleSpanDays | First to last stored sample span days | number |

}Limitations and assumptions
No compression, filesystem wear or indefinite retention is assumed.
Numbers and computed results must be finite; overflow produces an error. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Integrated Pest Monitoring Inspection Interval Scheduler: Schedule caller IPM inspection cadence from actual last events on continuous day ordinals, retaining overdue sign; no recommended monitoring interval or pest-free guarantee. For a complementary task, use RH Daily Fluctuation Tolerance Band Checker: Audit observed full-day RH range and resolved maximum slew as distinct caller fluctuation criteria; unresolved intersample extremes remain unknown.
