+* Temperature Logging
+** About
+This document was created by Steven Baltakatei Sandoval on
+~2020-10-24T23:37Z~ under a [[https://creativecommons.org/licenses/by-sa/4.0/][Creative Commons BY-SA 4.0 license]]. It was

+
+** Narrative
+The ~ninfacyzga-01~ device may log temperature readings from
+temperature sensors attached to it.
+
+Several types of temperature sensors may be equipped:
+
+- A model DS18B20 digital temperature sensor wired to one of the
+  Raspberry Pi Zero W's GPIO pins. Temperature readings may be read
+  via a ~python~ script.
+
+- An Ozzmaker BerryGPS-IMU temperature sensor (ex:
+  BMP388). Temperature readings may be read from a ~python~ script.
+
+- The Raspberry Pi Zero W's internal temperature CPU sensors
+
+Whatever the source, an associated ~python~ script should report the
+temperature in the form of JSON data sent to the script's standard
+output ("stdout") stream.
+
+In turn, this "stdout" is then piped into the ~bklog~ which takes care
+of packaging, encrypting, and appending the JSON data to a timestamped
+~tar~ file.
+
+~cron~ is used to call a single script which performs all of the above
+actions at regular time intervals.
+
+** Description
+*** Hardware
+- DS18B20 1-Wire Digital Thermometer
+- Raspberry Pi Zero W
+- Ozzmaker BerryGPS-IMU, Version 3 (see [[https://ozzmaker.com/berrygps-berrygps-imu-quick-start-guide/][ref]]).
+*** Software
