Connect SDI-12 USB adapter to a sensor

If you wonder how to connect your SDI-12 sensor to the SDI-12 USB adapter, here are two videos showing you how to. In the video, I was using a Decagon PRI spectral reflectance sensor. It comes with 3 wire leads. Bare wire is ground. Wire wire is power. Red wire is SDI-12 bus. If you purchased a Decagon sensor with the 1/4″ stereo plug, you can purchase an adapter from them that break out the wires into 3 wire leads.

The jeweler’s screw driver that I used was 0.1″ wide flat-head. On my next post, I will demonstrate how to run configuration and data logging scripts.
