Hello,
I have a hydra-probe II SDI-12 Stevens
the sensor has three wires
the first one should receive a 12 v to power it
the second one is ground
the third one is the SDI signal coming from the sensor
I know that the arduino does not read an SDI-12 signal that's why I ordered an SDI serial adapter shield to translate the SDI-12 signal to something the arduino can recognize.
the SDI-12 signal coming from the sensor has 9 parameters as indicated in the manufacturer data sheet(http://www.stevenswater.com/resources/documentation/hydraprobe/HydraProbe_Manual_92915_Jan_2015.pdf)
the SDI serial adapter that I ordered is this http://www.inmojo.com/store/liudr-arduino-and-physics-gadgets/item/sdi-12-serial-logger-shield/
the thing is right now I don't know how to go about connecting them together with an arduino and what kind code should be written in order to extract and store the data into an sd card
thanks.
