SDI 112 allows you to send commands directly to SDI 12 sensors connected to the iSIC First it is important to understand how 51 12 sensors work Sensors that adhere to SDI 12 protocol have a subset of commands that are consistent with every other SDI 12 sensor These commands are used to identify the instrument start a measurement get data etc Note Make sure that if there are multiple SDI 12 devices connected to the iSIC data logger that they each have a different SDI 12 address before sending SDI 12 commands The way a data logger works when an SDI 12 sensor is connected to it is that at a user specified interval the log or sample interval the data logger sends the measurement command to the instrument The SDI 12 sensor will then start taking a measurement and let the data logger know when it will be done doing so When the sensor has finished taking a measurement the data logger will ask the sensor for the data The sensor will return its data in a data string This string will look something like this 0 79 5 0 008 0 988 0 92 With each parameter separated by a plus sign One thing SDI 12 protocol does not do is tell the user what parameter and unit of measurement each returned value is This information therefore has to be specified in the software That is why it is important to know the exact order of parameters and the associated unit of measurement of each parameter returned Every SDI 12 sensor has a certain number of standard
