Em50 Logger Series Overview

The ECH O System is made of data loggers, sensors, telemetry, and
software that help you measure soil moisture and other environmen-
tal parameters accurately and cost effectively. Decagon's innovative
sensors are the heart of the system and we designed it to be very
easy to use (no programming needed).
The Em50 series loggers are 5-port, self contained data loggers espe-
cially suited for field research and commercial agriculture. The Em50
logger series includes three models: the Em50, the Em50R and the
Em50G. These devices are housed in a weather-resistant enclosure,
making them suitable for long-term outdoor operation.
Em50: The Em50 is the basic logger. The communication with
this model is through a Stereo to USB or Stereo to Serial cable to
a PC or mobile handheld device. An integrated solar panel is an
options for the Em50.
Em50R: The Em50R includes a spread-spectrum radio telemetry
module that delivers data to a DataStation. The radio module is
available in long-range 900 MHz. Use the telemetry in energy ef-
ficient transmit mode or two-way mode. (Section 6 provides more
information on telemetry.)
Em50G: The Em50G includes a GSM/GPRS (Global System for
Mobile communications/General Packet Radio Service) cellular mod-
ule to allow environmental measurement data transmission over the
Internet. Decagon partners with a provider of global cellular data
service to make data transmission and maintenance easy and in-
expensive. Measurements from the Em50G are sent wirelessly to
Decagon's Internet server and are available for download using Data-
Trac 3 software or the Em50G WebViewer. An integrated solar panel
is an option for the Em50G.
Em50 Compatible Sensors: You can use the Em50 to log data
