+
+What are some of the challenges of sensing temperature in both indoor and
+outdoor environments? We will attempt to peer into some of the challenges
+over the next five steps. Each step will involve recording the temperature
+while either performing an activity or going to a location around the Informatics Building.
+
+This short study was proposed by Rob M. Long for a Methods Activity as part of
+`Professor James Clawson's <https://jamesclawson.com/>`_ *"Field Deployments"*
+course.
+
+Instructions
+------------
+
+**First Run:**
+
+Manually record the start and end time for each event.
+
+1. *ProHealth Office:*
+
+  * Let the sensor collect data for five minutes while sitting at your desk.
+  * Copy and paste your data.
+
+2. *Outside:*
+
+  * Exit Informatics East through the north-east connector space door.
+  * Walk around the building (moving left through the parking lot) and stop in the courtyard.
+  * Sit at a bench for three minutes.
+  * Walk inside, stop recording, and copy and paste your data.
+
+3. *A Classroom:*
+
+  * Find an empty classroom. Record the room temperature for one minute.
+  * Turn off the lights in the room for two minutes.
+  * Turn the lights back on and continue recording for one more minute.
+  * Stop recording, copy and paste your data.
+
+4. *The Break Room:*
+
+  * Turn on the sensor and record for one minute.
+  * Place the sensor inside the fridge (or freezer) for three minutes.
+  * Remove the sensor, copy and paste your data.
+
+5. *The Random Walk:*
+
+  * Start recording from the Informatics East Lobby.
+  * Walk around the building for about five minutes, record where you go.
+
+**Second Run:**
+
+Repeat steps 2 & 3. This time: increase the delay time to ten seconds.
+
+.. code-block:: C
+
+  void loop() {
+    // --snip--
+    delay(10000);
+    startTime += 10;
+  }
+
+Methods
+-------
+
+This activity requires a
+`"SparkFun Digital Temperature Sensor Breakout TMP102" <https://www.sparkfun.com/products/13314>`_
+for measuring temperature, a `"SparkFun RedBoard" <https://www.sparkfun.com/products/13975>`_,
+a breadboard, and a five wires.
+
+One limitation is that all results are printed to the Serial Monitor. This
+means that a laptop will need to be carried to provide power and collect
+results.
+
+The following schematic shows how to wire the sensor to the board.
+
+.. raw:: html
+
+  <img src="https://github.com/batflyer/Informatics-Temperature-Study/blob/master/docs/svg/schematic.svg?sanitize=true" />
+
+The wires do not need to be the exact same colors. The labels are included so
+they can match the colors used here:

+  </p>
+
+Results
+-------
+
+Data are contained in the ``data/`` directory, split into ``data1.txt`` and
+``data2.txt``. The first contains steps 1-5, and the second contains steps
+2-3 when they were repeated with higher delay time.
+
+``data1.txt`` uses a 2-second delay time. ``data2.txt`` uses a 10-second
+delay time.
+
+``src/plot_data.py`` can be used to plot temperature vs. an integer.
+
+* The integers displayed on the x-axis represent the number of seconds after
+  ``12:00:02`` for the first set, and the number of seconds after ``12:31:30``
+  for the second set.
+* Since the temperatures and the dynamics were more of interest than the
+  actual times, the timestamps are left in the raw form.
+* The y-axis represents the temperature in degrees Fahrenheit, and the label
+  specifies which activity the temperatures correspond to.

+SparkFunTMP102.cpp
+SparkFunTMP102 Library Source File
+Alex Wende @ SparkFun Electronics
+Original Creation Date: April 29, 2016
+https://github.com/sparkfun/Digital_Temperature_Sensor_Breakout_-_TMP102
+
+This file implements all functions of the TMP102 class. Functions here range
+from reading the temperature from the sensor, to reading and writing various
+settings in the sensor.
+
+Development environment specifics:
+	IDE: Arduino 1.6
+	Hardware Platform: Arduino Uno
+	LSM9DS1 Breakout Version: 1.0
+
+This code is beerware; if you see me (or any other SparkFun employee) at the
+local, and you've found our code helpful, please buy us a round!
+
+Distributed as-is; no warranty is given.

+================
+``plot_data.py``
+================
+
+Plot the contents of the ``data/`` directory.
+
+Instructions
+------------
+
+1. This needs to be run from the base of the repository. For example:
+
+    .. code-block:: bash
+
+        $ pythonw src/plot_data.py -i 1     # Mac
+        $ python src/plot_data.py -i 1      # Linux
+
+2. ``-i FILE`` where FILE={1,2} sets which data set to plot.
+
+3. Images are not saved automatically. Make adjustments with the matplotlib
+   interface and save images locally.
