Appendix B. Example programs
B.1 CR1000X with one CS650 sensor
This CRBasic example program measures one CS650 sensor on a CR1000X every 15 minutes,
storing hourly averages of volumetric water content, electrical conductivity, and soil temperature
and samples of permittivity, period average and voltage ratio. The CS650 has an SDI-12 address
of 0. Wiring for the example is shown in
Table B-1 (p. 36).
