Hi all,
I’m in the throws of developing a remote monitor for off grid Wind Turbines, I’m a volunteer for a Non govermental organisation, installing small turbines where there’s no grid connection.
We’ve got a prototype collecting DC voltage and DC Current generated of our turbine, and logging data to an excel file, and user OverDrive (Linux version of Gdrive to sync that file to the internet).
I’m also (intermittently) able to send data to an IoT cloud service of ThingSpeak.
Current system is a sensor cricuit with 2 analogue inputs, connected to an Arduino, then a serial link via the USB to Raspberry Pi, and a Python script running a data logging script saving the file as a CSV and date stamp.
I’m trying to get my head around if using the emonPi Operating system would be a good move. Anyone got experience or insights they could share with me.
Is it straight forward to edit so as any data can be displayed on emonCMS as the final outcome, i.e. is the logging script, where the software expects data in a certain order e.g. Current Transformer 1, Current Transformer 2, Current Transformer 3… in mine would likely be DC Voltage Generated, DC Current Generated, Wind Speed, DC Voltage Consumed, DC Current Consumed.
From researching on this site I can see the standard install is a domestic AC supply, which logs data to the cloud service emoncms.
Any guidance would be greatly appreciated. I’ve got a little experience with Raspberry Pi, but still learning.
