EasyAG ® 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
