Description: Includes an SDI-12 example and a RS-232-serial program example. The programs are written for a CR1000X, but programs for other data loggers will be similar.
The SDI-12 example uses the C1! command to retrieve data. The program also adjusts the barometric pressure measurement to sea level. The adjustment is entered as a constant, Elevation_m, at the beginning of the program. Initially, the Elevation_m value is 1382; change this value to your site elevation, in meters.
The serial program demonstrates using RS-232 mode to initiate and return measurements using the SerialOut(), SerialIn(), and SplitStr() CRBasic instructions.
