OPERATION
2.2 CONNECTING
The ATMOS 14 works seamlessly with METER data loggers. The sensor can also be used with
other data loggers, such as those from Campbell Scientific, Inc. For extensive directions on
how to integrate the sensor into third-party loggers, refer to the
The ATMOS 14 sensor requires excitation voltages in the range of 3.6 to 15.0 VDC and
operates at a 2.8- to 5.5-VDC level for data communication. The ATMOS 14 can be integrated
using SDI-12 protocol. See the
for details on interfacing with data
acquisition systems.
The ATMOS 14 sensors come with a 3.5-mm stereo plug connector (
) to facilitate
easy connection with METER loggers. ATMOS 14 sensors may be ordered with stripped and
tinned wires to facilitate connecting to some third-party loggers (
).

The ATMOS 14 comes standard with a 5-m cable. It may be purchased with custom cable
lengths for an additional fee (on a per-meter basis). In some instances, the cable can be
extended beyond 75 m by the user, but this is discouraged for a variety of reasons. Please
contact
for more details before extending or splicing cables.
2.2.1 CONNECT TO METER LOGGER
The ATMOS 14 works most efficiently with ZENTRA series data loggers. Check the
for the most recent data logger firmware. Logger configuration may
be done using either ZENTRA Utility (desktop and mobile application) or ZENTRA Cloud
(web-based application for cell-enabled data loggers).
1. Plug the stereo plug connector into one of the sensor ports on the logger.
2. Use the appropriate software application to configure the chosen logger port for the
ATMOS 14. METER data loggers will automatically recognize ATMOS 14 sensors.
3. Set the measurement interval.
METER data loggers measure the ATMOS 14 every minute and return the average of the
1-min data across the chosen measurement interval.
ATMOS 14 data can be downloaded from METER data loggers using either ZENTRA Utility or
ZENTRA Cloud. Refer to the logger user manual for more information about these programs.
