Soil Water Content Profile Probes

Sample CR10X Program

Shaded portions of program can be omitted if TriSCAN sensors are not used.

;CR10X Datalogger

;Program Author: Campbell Scientific, Inc.

;Date: 04-12-06

;Description: Program measures 1 EnviroSMART / TriSCAN probe with 8 sensors or 1 EasyAG

; TriSCAN probe with 4 sensors. -1000 is loaded as the "measurement" for

; non-existant sensors. Program measures scaled frequencies, calculates

; water contents, and stores scaled frequencies, water contents, and

; volumetric ion contents separately. Scaled frequencies are stored with an

; "array identifier" leading 8 data values per record followed by 8 VIC per

; record, with the record ending with zero rain and irrigation values for

; compatibility with DBLOAD & Irrimax software.

;Assumptions: EnviroSMART or EasyAG probe SDI-12 interface is configured to output

; scaled frequencies

;Wiring: EnviroSMART / EasyAG 12 Volts (Pin 1)--------- CR10X 12 V

; EnviroSMART / EasyAG Ground (Pin 2)-------- CR10X Ground

; EnviroSMART / EasyAG Signal (Pin 3) --------- C7

; Rain Gage Pulse Out -------------------------------- CR10X P2

; Rain Gage Ground ----------------------------------- CR10X Ground
