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 lowbandwidth 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:
n Set up and maintain Connect Sensor
n Use Remote Manager to configure external sensors and data reports
n View 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.

Battery inspection
CAUTION! This product contains a lithium metal battery. Prior to installation, the
battery should be inspected for any signs of damage. If the battery appears to be
damaged or is dropped during installation, do not use the battery and dispose of it
properly.
Please contact Digi Technical Support at 952-912-3444 or Tech.support@digi.com to order a
replacement battery.
The MSDS (Material Safety Data Sheet) for the battery can be found at
www.digi.com/documentation/ConnectSensor.
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.
The battery will last 2 to 3 years in these conditions:
n Adequate cellular network coverage where Connect Sensor is installed
n Connect Sensor sends reports to Remote Manager a maximum of two times a day
n Connect Sensor is not powering high-current sensors with long read delays
The temperature at the device's location also affects the battery. Battery power is used more quickly
in a cold environment than in a warm environment. A battery in a device located where the
temperature is consistently 20° F will not last as long as a battery in a device located where the
temperature is consistently 80° F.
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.
Note When using the Continuous Monitoring feature, it is recommended that you use an external
power source rather than relying on the battery within Connect Sensor. See CSENSE Continuous
Monitoring power source for more information.
Battery percentage ranges and replacement
When the battery life percentage is above 30%, the battery has enough power to power the device,
and the device will function as expected.
Digi Connect® Sensor User Guide

Hardware Battery percentage and external power
When the battery life percentage drops below 30%, the battery power is low and, depending on the
conditions in which the device is operating, may cease to power the device. To ensure that readings
continue as expected, it is recommended that you change the battery when the battery percentage
decreases to 30%. See Battery replacement.
You can view the battery life percentage in Remote Manager. See View battery life for a device in
Remote Manager.
Battery passivization
Unused lithium batteries that have been in storage acquire a state of passivization that can cause the
battery to report a low battery percentage for a time after initial installation. As the device uses the
battery, the passivization is removed and the battery percentage increases to a maximum of 90 100% (depending on the temperature). The passivization removal process could take a week or more,
if the number of times Connect Sensor wakes to take sensor readings and send reports to Remote
Manager is once per day or less.
Note Passivization may never be removed if the device sends reports to Remote Manager too
infrequently.
Battery percentage and external power
The device is powered by either external power connected to the device, or by an internal battery that
is connected to the device. The device is not powered by both power sources at the same time.
You can view the battery life percentage for a device in Remote Manager. See View battery life for a
device in Remote Manager. The battery life percentage depends on whether the device is using the
external power source or the battery.
n If the device is using the external power source and the battery is connected to the device,
then the battery life is 100%. This will occur whether the battery has any battery life remaining
or is dead.
n If the device is using the external power source and the battery is not connected to the device,
then the battery life is 0%.
n If the device is not using external power and the device is using the battery, the actual battery
life percentage displays, and is a percentage other than 100% or 0%.
CSENSE Continuous Monitoring power source
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.

Firmware
This section includes information about the Connect Sensor firmware options that are available in
addition to the standard firmware. These firmware options provide additional features. Note that
these firmware options contain all of the features in the standard Connect Sensor firmware in
addition to the features available in the firmware option you select.
If you want to use any of the optional features, you must upgrade from the standard Connect Sensor
firmware to the firmware variant that includes those features. The firmware upgrade can happen only
when Connect Sensor is awake and connected to Remote Manager. Any firmware upgrades,
configuration changes, or commands that have been added to a schedule in Remote Manager are
pushed to Connect Sensor at that time. If you need to upgrade the firmware before a scheduled push
from Connect Sensor, you can physically wake the Connect Sensor device to force a connection
between Connect Sensor and Remote Manager. For information on how to update the firmware, see
Firmware updates.
CSENSE Continuous Monitoring firmware
Note It is strongly recommended that an external power source for the Connect Sensor device is used
with continuous monitoring.
For some customers, the scheduling paradigm of the standard Connect Sensor offering is inadequate.
With continuous monitoring, Connect Sensor can constantly monitor sensors for an alarm by
continually sampling sensor data. This enables Connect Sensor to find alarms faster, and to not miss
any alarms that may have occurred between scheduled sensor readings.
The Connect Sensor device should be configured to specify a buffer time range for before and after an
alarm occurs. When an alarm occurs, Connect Sensor continues to sample data until the time limit of
the buffer is reached. When the buffer time limit is reached, the following information is pushed to
Remote Manager:
n Sample data in the buffer for the time range specified
n Alarm information
n Information from a scheduled reading stored in the device's memory
In addition to continuous monitoring, scheduled sensor readings still occur, and that data is stored in
the Connect Sensor memory.
n If a sensor alarm occurs, the data samples taken during the buffer time range plus any other
diagnostic information stored in the device's memory is pushed when the buffer time range is
reached.
n If an alarm doesn't occur between scheduled pushes, the information from a scheduled reading
stored in the device's memory is pushed to Remote Manager as scheduled.
