PC/Mac/Linux/Raspberry PI compatible data logger
SDI-12 USB 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 and Analog sensors with a PC/Mac/Linux/Raspberry PI, on a budget. I have built numerous SDI-12 sensor data loggers. This is my latest design that is very easy to use. All you need is the adapter and a PC/Raspberry PI. It also comes with free data logger program (Python script) for all operating systems. A section on SDI-12 sensors will guide you through it. A $35 Raspberry PI 2B will be more than sufficient.

Features
SDI-12 USB Adapter, SDI-12 USB + Analog Adapter

  • Connects SDI-12 sensors directly to PC/Mac/Linux/RPI over USB
  • 3-pin SDI-12 interface on screw terminal block
  • Fuse protected

  • SDI-12 USB + Analog adapter only
  • 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
  • External power connection
  • Ext. or 5V power selector
  • 4 SDI-12 connections for convenience


  • Sensors tested

    So far, I have been able to get hold of the following sensors and tested them all with the adapter. In theory, all SDI-12 sensors should work with my adapter but in practice not all sensors were made equal. The following list will keep expand as I get more sensors to test.
    Apogee:
  • SI-411 (standard field of view infrared radiometer)
  • Aquacheck:
  • CKC 6 sensor probe
  • Campbell Scientific:
  • CS650 Soil Volumetric Water Content Probe
  • CS655 Soil Volumetric Water Content Probe
  • Decagon:
  • DS-2 (Sonic Anemometer)
  • VP-3 (temp., barometer, humidity)
  • PRI (spectral reflectance)
  • NDVI (spectral reflectance)
  • GS3 (Ruggedized Soil Moisture, Temp., and Electrical Conductivity)
  • MPS-6 (Calibrated Water Potential Sensor)
  • 5TM (Soil Moisture and Temp.)
  • Ponsel:
  • Digital turbidity sensor
  • Sentek:
  • TriSCAN
  • PT1000



    Data Logging (WIN 10/Mac/Linux/Raspberry PI)
    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/Raspberry PI 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 raspberry pi 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. With Python data logger code V1.1 and up, your data is sent to a sparkfun data server. You can retrieve data remotely.
