| 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. | |
