Hello @d_bozza123, the Ponsel sensor looks very interesting.
I’ve interfaced to a SDI-12 sensor Insitu LT500.
My suggestion is you think of breaking up the work into units.
That is first how to read the sensor Ponsel, and 2nd how to store it to the .csv
For my sensors, it required creating a sensor interface to read the parameters from the instrument.
or similarly in my case https://github.com/neilh10/ModularSensors/blob/release1/src/sensors/InsituTrollSdi12.h
Then in the program file eg “simple_logging.ino” create the sensors
See Variable* variableList = in https://github.com/EnviroDIY/ModularSensors/blob/master/examples/simple_logging/simple_logging.ino
To think of LoRa is a great idea, and a number of people are thinking about it. So just curious where it would visualize the data on the internet?.
A smaller step would be to post to MonitorMyWatershed.org over a cellular modem LTE to learn about the flow of data?
One of the issues with LoRa might be how is wall time synced to the mayfly?
