UPDATE 3/1/18 @3:30PM I’m pretty stoked. The depth measurement system is at 329mm which is 1.08 ft. Compares well to the snow pole visual (it did at the time) UPDATE: 1/14/18 @ 5:02 PM After another several hours of … Continue reading

UPDATE: 1/13/18 @ 3:48 PM Even more progress! The service is installed and waiting for me to restart weewx (the weather station software). It’s been a long day and I’m to tired to do any more troubleshooting so I’m going … Continue reading
I started the morning writing a test script and starting the debug process which I expected to go quickly. About 4 hours later I had the software working the way I expected it to run. Most of the problems I … Continue reading
Two important components arrived today. One was the 3/4″ -14 NPS die I needed to couple the sensor to standard 3/4″ PVC or steel pipe. $50 for this thing and it took 5 minutes to modify a threaded PVC fitting … Continue reading
After doing more research and trying a few things I managed to: Figure out how to configure and test the UART / serial port and it was still working. Figure out how to connect to the Ultrasonic Sensor and it … Continue reading
Well, I got the sensor all wired up, plugged it into it’s own power supply as recommended by the manufacturer and… no joy! The power supply I used, again as recommended by the manufacturer, is a 5 v supply. The … Continue reading
This morning I edited the two Python scripts that will be used on the measurement machine to talk to the Ultrasonic Sensor to get the snow depth data. The first time I ran a test without the sensor connected I … Continue reading
I spent all morning figuring out how to get the remote execution of Python scripts working. What a PITA! It turns out that when you log in through SSH, or in my case SFTP, you get handed a completely PATH … Continue reading
While I await some parts needed to connect the sensor to the measurement system (Raspberry Pi 3) I am going to spend most of the day today doing some research and planning for next steps. One thing I have not … Continue reading
This morning I added a DS3231 Real Time Clock to the measurement system Raspberry Pi. I used THIS article to guide the way. One mistake that I made at the end of the process cost me a lot of time. … Continue reading
