SDI-12 Sensor Inputs with the Sutron Datalogger
The Sutron 9210B datalogger records biomet data in LI-COR eddy covariance systems. In addition to measuring analog voltage inputs, it can also record data transmitted via the SDI-12 communications protocol from up to ten sensors. Programming a sensor with SDI-12 output requires an extra step—the sensor must be given a unique address. In this example, we connect a Stevens Hydra Probe II soil moisture/temperature sensor to the datalogger.
1. Power on the datalogger, and connect to it with the…
