SDI-12 Sensor Reader

The Acclima SDI-12 Sensor Reader / Data Logger Kit is the essential interface device for connecting and reading Acclima TDR soil moisture sensors (or any SDI-12 compatible sensor). It enables real-time monitoring, waveform capture (for TDR sensors), data logging, GPS tagging, USB export and portable field use. Designed for professionals in agricultural research, irrigation management, soil moisture monitoring and environmental instrumentation, this kit bridges high-precision sensors and usable data.

The unit supports the SDI-12 communication protocol and comes in a rugged, portable form factor. It is ideal when you want to deploy the TDR sensors (such as Acclima TDR-315H/310H) in the field and then connect to a “meter” unit that will collect, display and store their readings for analysis or export.

Key Features

• • Compatible with all SDI-12 sensors (including TDR / TDT sensors).
• • Waveform capture capability: for “Waveform Capture” sensor models, the reader will display the waveform data.
• • Built-in GPS connectivity for tagging sensor location.
• • Rugged, portable kit: includes carrying case, power adapter, 32-GB thumb drive for data export.
• • Plug-and-play: no SDI-12 programming expertise required for standard use.
• • Compatible data logger/reader options: e.g., DataSnap SDI-12 Data Logger, Solar DataSnap, Sensor Reader Kit.

Applications

• • Field deployment: Collect real-time soil moisture, EC and temperature from Acclima TDR sensors in the field for irrigation/fertilizer scheduling.
• • Research & monitoring: Link multiple sensors to a logger/reader to map soil moisture profiles, root-zone moisture response, water stress, etc.
• • Portable troubleshooting: Use the reader kit in mobile mode to check sensor installation, verify waveform capture, check sensor health and site-specific data.
• • Long-term monitoring: Use solar-powered data logger version (Solar DataSnap) to collect multi-year data in remote sites.

User Benefits

• • Turns high-precision sensor data into usable logged data for analysis, reporting and decision-making.
• • Simplifies sensor integration: supports multiple sensors, export via USB, minimal programming required.
• • Field ready: portable, rugged, supports waveform capture—ensures sensor is performing, not just plugged in.
• • Extends versatility of sensors: allows users to deploy sensors across multiple zones/sites and monitor through a single reader/logger system.
• • Helps reduce manual readings, improves data consistency, supports better irrigation/water-use management decisions.

Best Practice / Considerations

• • Make sure the data logger/reader version is compatible with the number of sensors you plan to deploy (e.g., up to 10 sensors for DataSnap).
• • Ensure field wiring follows the SDI-12 guidelines: correct cable gauge, sensor addresses set uniquely, minimal voltage drop on bus.
• • For mobile reader use (Sensor Reader Kit), ensure the firmware is updated periodically — check manufacturer for updates.
• • In remote deployment (e.g., Solar DataSnap), ensure solar panel and battery size are suited for your location’s sunlight and seasonal conditions.
• • Even though the reader kit supports standard use without SDI-12 programming, advanced users may configure thresholds, logging intervals and export formats via provided software (SnapView).
