Acclima's sensor represents the Gold Standard is soil moisture sensing technology. The Center for Irrigation Technology in Fresno, CA put the sensor through a battery of test comparing it with laboratory equipment costing thousands of dollar. The sensor out-performed the laboratory equipment. Click here to see the full study.

Digital TDT® Moisture Sensor SDI

Because of Acclima's patented digital technology the sensor never needs calibration and works in any soil type. Designed for permanent installation the maintenance free sensor is a powerful tool for soil scientists and researchers.

The original Digital TDT sensor is available for use for research with the SDI-12 protocol communications standard. The sensors with SDI interface can be used with commercially available data loggers using the SDI protocol.

NOTE: SDI sensors cannot be used with irrigation controllers and are designed only for use with data loggers or RS232 interface using the separate adapter.

SDI RS232 Interface Adapter

Transform your computer into a moisture data logger! Using the SDI Adapter you can connect up to five SDI sensors into a RS232 serial cable which can be connected to a PC. Using the Data Manager software provided by Acclima you can log data from the sensors for research. The adapter creates an interface between the SDI protocol and RS232.

Multiple sensors can be connected to one adapter (up to five) and placed at different depths to ge a real-time profile of the soil moisture activity.

The adapter includes a 120v transformer.
