Hi everyone
in this opportunity I want to consult
What is the hardware or modules required to design a datalogger that stores modbus data from an aqua troll 200 probe?
From already thank you very much
This probe seems to have 4-20mA, RS485(MODBUS) and SDI-12 interface.
SDI-12 interface commands can be found in their site - https://in-situ.com/pub/media/support/documents/SDI-12-Commands-and-Aqua-TROLL-100-200-Responses.pdf
Others protocol details is provided after you bought the probe based on their pdf specs.
All these three interfaces is available in our WisBlock Interface categories - WisBlock Interface modules from RAKwireless – RAKwireless Store
However, you have to write your own code on this based on the commands provided by the probe manufacturer.
