-Optionally:
+  - Connect the tipping bucket to the large port on the sensor
-  * a multimeter/power sensor,
+  - Connect the four colorful wires to the proper GPIO Pins (See above)

+  - On a Raspberry Pi, to make the code given by the ADPAA work, you will have to enter the following command into your terminal
-  * some apparatus that can introduce humidity (e.g. a half-full gallon of water),
+    - sudo pip3 install modbus_tk smbus - -break-system-packages
-  * and an apparatus that can introduce heat (e.g. a heat gun, or even your hand).
-  - Connect the DC Power Jack to power
-    - Connect the red wire to the positive connection
-    - connect the black wire to the negative connection
-  - Optional: If you would like to test the probe prior to connecting it, follow this step. You will need the optional materials. If you do not want to test the probe, skip to step 3.
-    - Temperature
-      - Using the multimeter, connect the clamps to the exposed ends of the yellow and white wires.
-      - Change the setting till you see a readable number.
-      - Using your heating apparatus, gently heat the probe and observe the signal increase
-    - Humidity
-      - Connect the multimeter's clamps to the exposed ends of the blue and white wires.
-      - Change the setting till you see a readable number.
-      - Using your humidity apparatus, carefully introduce the sensor to a humid environment and observe the signal increase.
-  - Wire the probe into the DAQ HAT
-      - Connect the yellow wire to CH4
-      - Connect the blue wire to CH5
-      - Connect the white wire to GND, next to CH5
-  - If you have properly set up the ADPAA and DAQ HAT, you can now run the python program that coincides with your instrument and observe the data.
