With 32 times the memory of our
Weather Envoy, Envoy8X receives and
logs data simultaneously from up to
eight transmitting stations, in any
combination—even eight Integrated
Sensor Suites or eight Leaf Wetness
& Soil Moisture/Temperature Stations!
Doing the math, that means you can get
data from 32 soil moisture sensors on
one Envoy8X! Includes robust software
that allows for data from many sensors
and multiple Envoy8Xs to produce very
large databases in Microsoft Access
®
,
MySQL
®
, or Microsoft SQL Server
®
. You
select which sensors to log, and choose
a logging interval from 10 seconds to 2
hours. You can even add select third-party
sensors that report readings in a 0–3 volt
range. Data can be easily exported to
a spreadsheet program such as Excel
®
,
or to WeatherLink to take advantage of
WeatherLink’s graphing and reports.
Storage capacity depends upon the
logging interval, but is so large that you
can download a remote field installation
when it’s most convenient. For example,
an Envoy8X logging two Integrated Sensor
Suites and two Soil Moisture/Leaf Wetness
stations at a 15-minute update interval will
store  worth of data.
Envoy8X has built-in temperature and
humidity sensors, as well as a barometer.
The software will report data from those
sensors as “inside” data, effectively giving
you a ninth “station.” You may connect
an external temperature probe (6475 or
6477) to replace the Envoy8X’s internal
temperature probe (see page 14). Receives
