10.2 Programming Example 2
SR50AT SDI-
12 “M3!” CR10X Datalogger
;{CR10X}
;
;In this example, the SR50AT is mounted 2.5 meters above the ground.
;
;The CR10X sends an SDI-12 command to the SR50AT, which outputs the
;temperature compensated distance value (Meters),
;the signal quality value and the temperature.
;
;Three input locations are used to store incoming data.
