I’m about to set off on using an ultrasonic 4-20 sensor for water level measurement; first time through using this technology.
The sensor is this one (which I happen to have on hand already):

Can someone point me to plan, sites, devices which would enable me to get the output of the sensor into a tab/space delimited format for use in an SQL table?
Grateful for any pointers.
print(), in its many forms, on any computer, works.
You kind of need to approach this from both ends.
On the front end you have this sensor which needs a power supply and outputs analog 0-10V.
Your CSV recording device needs an analog input to interface to.
On the back end you have your SQL table - where is this and what does it run on? Windows, Linux? PC or Raspberry PI?
Whatever it runs on needs to be able to access the CSV file.
The CSV file is easily generated on most devices but you likely need to write a program to sample the level measure device periodically and write the values.
