PC Win 7/10/Mac/Linux/Raspberry PI/Beagle Bone Black compatible data logger
SDI-12 USB adapter, SDI-12 USB + GPS adapter, and SDI-12 USB + Analog adapter


SDI-12 sensors are widely used in environmental monitoring including soil, streams, plants etc. On the other hand, data loggers designed for SDI-12 sensors are usually expensive and proprietary, making it harder to monitor and study soils and streams on a budget. This SDI-12 USB adapter makes it possible to directly interface SDI-12, Analog sensors, and GPS with a PC/Mac/Linux/RPI/BBB, on a budget. I have built numerous SDI-12 sensor data loggers. This is my latest design that is very easy to use. It also comes with free and open-source data logger program (Python script) for all operating systems. A section on SDI-12 sensors will guide you through it. A $35 Raspberry PI is more than sufficient to log data.

All SDI-12 USB Adapters

  • Connects SDI-12 sensors to PC/Mac/Linux/RPI/BBB over USB
  • 4 SDI-12 screw terminal block connections for convenience
  • Ext. or 5V power selector
  • External power connection
  • Fuse protected

  • Additional features: SDI-12 + GPS
  • GPS coordinates, date, time, speed (GPS module sold at adafruit.com item 746)

  • Additional features: SDI-12 + Analog
  • 4-analog auto-scaling single-ended channels up to 20uV precision
  • 2-analog auto-scaling differential channels up to 20uV precision
  • Precision 1K or 10K pull-up resistors for resistive sensors

  • Sensors tested
    In theory, all SDI-12 sensors should work with my adapter. I have so far tested these sensors to work:

    Apogee: SI-411 (standard field of view infrared radiometer)
    Aquacheck:CKC 6 sensor probe
    Campbell Scientific:
  • CS215 Air Temperature and Rel. Humidity
  • CS650 Soil Volumetric Water Content Probe
  • CS655 Soil Volumetric Water Content Probe
  • Decagon:
  • DS-2 (Sonic Anemometer)
  • VP-3, VP-4 (temp., barometer, humidity)
  • PRI SRS and NDVI SRS (spectral reflectance)
  • GS3 (Ruggedized Soil Moisture, Temp., and Electrical Conductivity)
  • MPS-6 (Calibrated Water Potential Sensor)
  • 5TE (VWC, EC, and Temp.)
  • 5TM (Soil Moisture and Temp.)
  • Gill Instruments: WindSonic Ultrasonic Wind Sensor
    HSTI: HydraSCOUT multi-sensor soil moisture and temperature probe
    METER group (formally Decagon): Atmos14, Atmos 22, Atmos 41, PRI, NDVI, GS3 TEROS 21, ECH2O 5TE, ECH2O 5TM
    Ponsel:Digital turbidity sensor
    Sentek:TriSCAN probe
    Sutron: Accubar Barometric Pressure Sensor, Model 5600-0120-3

    Analog sensors (SDI-12 + Analog):
  • Apogee SP-110 Self-Powered Pyranometer
  • PT1000



  • Data Logging (WIN 7/10/Mac/Linux/RPI/BBB)
    Manual and data logging scripts from my blog (scroll to bottom):

    https://liudr.wordpress.com/gadget/sdi-12-usb-adapter/

    You can sit back and watch the PC/RPI/BBB data collection Python script collect data automatically
  • Sensor address
  • Total data points
  • Delay between data points
  • GMT or Local time zone



  • Just run the data logger script in Python. Your data will be stored where this script is so if you store the script in a cloud drive, you will be able to view your data remotely.

    File Format
    Your data will be stored in comma-separated-value (.CSV) format. The file name is the date and time when the script starts logging data. There are at least three columns. The first column is the date and time the data point is collected. Depending on your choice, it is either in GMT/UTC or local time. The next column is the sensor address. The third column is the first value returned by your sensor. If your sensor returns more than one value, additional columns will contain additional values.
    This file format is ready to be read by any major data analysis tools such as Excel, Open Office Calc, or the more expensive Origin Pro. Here is a sample of data collected from a Decagon 5TM soil temperature and moisture sensor. The first data column is the relative dielectric constant (1 for air, yes, it’s NOT in soil). The second data column is temperature.

    Telemetry
    Your PC or RPI/BBB must have access to the internet. Your data are sent to a server and stored there ready for retrieval and plotting in a web browser.
