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.\u00a0 The first time I ran a test without the sensor connected I got an error indicating that the script did not have permission to access the serial port where the sensor is to be connected.\u00a0 I changed the permission on the port using:<\/p>\n
sudo chmod 777 \/dev\/serial0<\/p>\n
Then the scripts worked but as expected returned an error since no sensor was connected.\u00a0 I just need to modify how the results are printed out once I get the sensor is connected and that part of the system should be pretty much done other than making a mount for the sensor on the Snow Pole and running a cable out to it.<\/p>\n
Over the past couple days I have done a lot of research into how to implement the weather system side of things and I’ve found a very slick approach.\u00a0 Apparently, over the last 7 or so years since I started using WeeWx to gather the weather station data, a lot of changes have been made.\u00a0 One of those changes is a very tidy way to add extensions like I want to do with snow depth measurement.\u00a0 I am going to start working on the new extension package today.<\/p>\n
