About Digi Connect® Sensor
Connect Sensor is a low-power cellular sensor gateway for wireless drop-in networking to remotely
monitor industrial environments and control systems, such as pipeline flow, air pressure, and light
levels. To power Connect Sensor, use either the internal battery or an external power source, such as
solar panels, for setups with no power or limited power.
Connect Sensor includes an external input/output (I/O) interface inside a waterproof enclosure for
connecting third-party sensors. The sensors gather information (sensor readings) from their
environment, and Connect Sensor reports that information to Digi Remote Manager® using a low-
bandwidth cellular connection. You can sign in to your Remote Manager account to view the reports or
use the Digi Connect Wizard app on a mobile device and pair it with a nearby Connect Sensor to view
real-time sensor and device data in the field.
Note Make sure there is adequate cellular network coverage where you plan to install the gateway
before purchasing cellular service.
This guide shows you how to:
nSet up and maintain Connect Sensor
nUse Remote Manager to configure external sensors and data reports
nView sensor data and Connect Sensor system information
See the Digi Connect Sensor I/O Wiring Guide for details about wiring analog or digital I/O sensors and
power to Connect Sensor.
Digi Device Cloud and Digi Remote Manager
Note To serve our customers most effectively, Digi International Inc. is consolidating its cloud
services, Digi Device Cloud and Digi Remote Manager®, under the Remote Manager name. This phased
process does not affect device functionality or the functionality of the web services and other
features. However, you will find instances of both Device Cloud and Digi Remote Manager in some
documentation, firmware, and user interfaces.

Battery life
Connect Sensor uses sleep and wake modes to manage power use. The device wakes only for sensor
readings and sending reports to Remote Manager. It is in sleep mode at all other times to maintain
low power consumption.

About Digi Connect® Sensor Connect Sensor product specifications
Digi Connect® Sensor User Guide 11
The battery will last 2 to 3 years in these conditions:
nAdequate cellular network coverage where Connect Sensor is installed
nConnect Sensor sends reports to Remote Manager a maximum of two times a day
nConnect Sensor is not powering high-current sensors with long read delays
Extend battery life by scheduling less frequent sensor readings and reports. Scheduling more frequent
sensor readings and reports may shorten the battery life to less than 2 years.
Continuous Monitoring Feature
For some customers, the scheduling paradigm of the standard Connect Sensor offering is inadequate.
Digi offers an alternate firmware image that trades alarm reactivity for power consumption. The
CSENSE Continuous Monitoring firmware image can be downloaded and installed on a Connect
Sensor.
When using the continuous monitoring feature, Connect Sensor never sleeps. For best performance
and ease of use it is recommended that you use an external power source rather than relying on the
battery within Connect Sensor. If the battery is used, the battery life is significantly reduced. The
Connect Sensor battery can be used as a short-term battery backup if the external power source fails.
For more information about the continuous monitoring feature, see CSENSE Continuous Monitoring
firmware.
