6.6.4 CR10X With a Single CS650 Probe

This Edlog example program measures one CS650 probe on a CR10X every 15

minutes, storing hourly averages of volumetric water content, electrical

conductivity, soil temperature, permittivity, period average, and voltage ratio.

The CS650 has a SDI-12 address of 0. Wiring for the example is shown in
