The PR2 SDI-12 is a new digital alternative to the well-established analogue PR2 Profile Probe.
It shares the many strengths of the analogue PR2 soil moisture probe, but with the addition of SDI-12 compatibility – allowing integration into new and existing SDI-12 systems.
The PR2 SDI-12 Profile Probe builds on the reputation and field proven technology of the analogue PR2. By adopting the widely used SDI-12 interface (v1.3) the PR2 SDI-12 can be integrated with an even wider range of data loggers, sensors and equipment.
SDI-12 is an established communication standard adopted by many manufacturers of environmental monitoring and control equipment. It is popular because it allows large numbers of sensors (from many vendors) to be connected to a logger via a simple cable network, thereby reducing the cost and complexity of wiring large sensor installations.
