| | 10 | ** Narrative |
| | 11 | The ~ninfacyzga-01~ device may log temperature readings from |
| | 12 | temperature sensors attached to it. |
| | 13 | |
| | 14 | Several types of temperature sensors may be equipped: |
| | 15 | |
| | 16 | - A model DS18B20 digital temperature sensor wired to one of the |
| | 17 | Raspberry Pi Zero W's GPIO pins. Temperature readings may be read |
| | 18 | via a ~python~ script. |
| | 19 | |
| | 20 | - An Ozzmaker BerryGPS-IMU temperature sensor (ex: |
| | 21 | BMP388). Temperature readings may be read from a ~python~ script. |
| | 22 | |
| | 23 | - The Raspberry Pi Zero W's internal temperature CPU sensors |
| | 24 | |
| | 25 | Whatever the source, an associated ~python~ script should report the |
| | 26 | temperature in the form of JSON data sent to the script's standard |
| | 27 | output ("stdout") stream. |
| | 28 | |
| | 29 | In turn, this "stdout" is then piped into the ~bklog~ which takes care |
| | 30 | of packaging, encrypting, and appending the JSON data to a timestamped |
| | 31 | ~tar~ file. |
| | 32 | |
| | 33 | ~cron~ is used to call a single script which performs all of the above |
| | 34 | actions at regular time intervals. |
