Introducing the Smoke Sensor Data Migration

1. Check raw data

Since the time intervals are in nanoseconds, it seems necessary to set new time values at 1-second intervals.

2. Set the Preprocessing Plan

  • Data reorganization.
    • Make new time values at 1-second intervals.
    • Convert to the format: Name, Time, Value & Convert to UTC time.

Data reorganization

  • Make new time values at 1-second intervals.
  • Convert to the format: Name, Time, Value & Convert to UTC time.

Once the data frame is restructured as shown in the image below, it will be ready for upload to Machbase Neo.

3. Data Upload

Finally, the data can be uploaded to Machbase Neo using the command below.

machbase-neo shell import --input ./datahub-2025-3-Smoke.csv.gz --compress gzip --header --method append --timeformat ns smoke

Check the entire code.

As an event approaches, it is worth considering how details related to cosplay costumes will affect the complete look. When comparing costume options, reviewing details related to shoes and accessories also makes comfort and movement easier to judge. To compare practical details about details related to cosplay shoes, women's cosplay costumes for game fans offers a useful starting point for practical preparation. To stay comfortable throughout the event, it is useful to check details related to shoes and accessories against the wearer's own needs.
