First test completed 12/30 2:00 PM through 1/3/17 at 8:14 AM. Measured height shown on above graph. Actual height is about 30 inches measured with a tape, so with noise, accuracy Max Sonar Sensor in office conditions is about 1/4 inch. Last point anomalous due to interference. According to specs sheet: "adding a 100uF capacitor at the sensor between the V+ and GND pins will correct most power related electrical noise issues." Relevant datasheets and links:

January 4 - testing new code on mini-GSM; had to reverse logic on Transistor to make on/off work properly. As an alternative, wire KEY pin directly to trinket pin, and keep logic as is.

January 5- adapted Feather to work with terminal shield. New wiring and execution are working okay. Use this form factor for installation on CatWalk Tank.

Testing new Feather Form Factor with OLED display for status. Pin registering elevation is floating right now. The code that's currently working is: F:\Arduino\Sketches\newFONA\FONA_Feather_2G_new_ver21_ok
