Hello colleagues, another problem, i tried to use Grove EC sensor to check water quality in my aquarium.
But all examples work with DFRobot_EC which does all calculations. But it also uses EEPROM.h where is little issue.
I found this nice example https://www.seeedstudio.com/blog/2020/09/29/biofloc-monitoring-system-powered-by-wio-terminal-m/
but i dont know how is done, because i get always compiling error.
I am able to read raw sensor data, but i dont know the calculation formula.
for example how to get from 1.17 something … 637 microSiemens
many thanks
Ed
compiling error ？ can you show it to us ？
Hello!
I have the same problem, I have the Wio Terminal and Grove EC Sensor and downloaded the Arduino library. I loaded the DFRobot_EC_Test and when I tried to compile it I got the error Error compiling for board Seeeduino Wio Terminal. See below for the details
