SDI-12 Address Menu
Intro to SDI-12
SDI-12 stands for serial data interface at 1200 baud. This
standard was created to interface battery powered data
recorders (loggers) with micro-processor based (intelli-
gent) sensors designed for environmental data acquisition
(EDA). Please see www.sdi-12.org for more information
on using SDI-12.
Decagon’s digital soil moisture sensors communicate us-
ing both the SDI-12 standard and Decagons proprietary
protocol. This SDI-12 feature is not necessary when using
Decagon sensors with Decagon data loggers. But, SDI-12
may be useful if you are using the sensors with other third
party data acquisition systems such as Campbell Scientific
data loggers.
One feature of the SDI-12 protocol is the use of a single
charactor sensor address. This character may consist of “0”
(default) to 1-9, a-z, or A-Z. This address is necessary when
multiple sensors are installed at a single site. This is impor-
tant because you will need to assign each sensor a different
address thus allowing you to keep their data separate.
