ABOUT THE WIRELESS CO² SENSOR
The ALTA Wireless Carbon Dioxide (CO²) Sensor measures the amount of CO² in the ambient air surrounding the element. It is programmed to take readings at a set interval to accurately calculate CO² levels, then send the time-stamped data to the iMonnit Online Sensor Monitoring and Notification System at user- specified time intervals (sensor heartbeat). The CO² data can be reviewed and exported as a data sheet or graph and notifications can be set up through the online system to alert the user when defined thresholds have been met or exceeded.

ORDER OF OPERATIONS
It is important to understand the order of operations for activating your sensor. If performed out of sequence, your sensor may have trouble communicating with iMonnit. Please perform the steps below in the order indicated to make sure you are performing your set-up correctly.
-
Create an iMonnit Account (If new user).
-
Register all sensors and gateways to a network in iMonnit.
Sensors can only communicate with gateways on the same iMonnit network. -
Connect/power on the gateway and wait till it checks into iMonnit.
-
Power on the sensor and verify it checks into iMonnit.
We recommend powering the sensor near the gateway then moving to the installation location, checking signal strength along the way. -
Configure sensor for use (This can be done at any point after step 2)
-
Install the sensor in the final location.
Note: For information on setting up iMonnit and the gateway refer to the
iMonnit User Guide and the gateways user guide.
Note: Device-specific setup is covered in more detail in the following
sections.
SETUP AND INSTALLATION
If this is your first time using the iMonnit online portal, you will need to
create a new account. If you have already created an account, start by logging
in. For instructions on how to register and setup your iMonnit account, please
consult the iMonnit User Guide.
STEP 1: ADD DEVICE
-
Add the sensor on iMonnit.
Add the sensor to your account by choosing Sensors in the main menu.
Navigate to the Add Sensor button.
-
Find the device ID. See Figure 1.
The Device ID (ID) and Security Code (SC) are necessary to add a sensor.
These can both be located on the label on the side of your device. -
Adding your device. See Figure 2.
You will need to enter the Device ID and the Security Code from your Sensor in the corresponding text boxes. Use the camera on your smartphone to scan the QR code on your device. If you do not have a camera on your phone, or the system is not accepting the QR code, you may enter the Device ID and Security Code manually.
• The Device ID is a unique number located on each device label.
• Next, you’ll be asked to enter the Security Code from your device. A security code consists of letters and must be entered in upper case (no numbers). It can also be found on the barcode label of your device.
When completed, select the Add Device button.
STEP 2: SETUP
Select your use case. See Figure 3.
Unlike most sensors, choosing a use case in Step 2 of adding this sensor
does not give you the option to customize your settings.
These will need to be adjusted in the settings tab for your device. See page 9
for instructions.
Select the Skip button when completed.
STEP 3: VALIDATION
Check your signal. See Figure 4.
The validation checklist will help you ensure your sensor is communicating
with the gateway properly and you have a strong signal.
Checkpoint 4 will only complete when your sensor achieves a solid connection
to the gateway. Once you insert the batteries (or flip the switch on an
industrial sensor) the sensor will communicate with the gateway every 30
seconds for the first few minutes.
Select the Save button when completed.
STEP 4: ACTIONS
Choose your actions. See Figure 5.
Actions are the alerts that will be sent to your phoneor email in the event of
an emergency. Low battery life and device inactivity are two of the most
common actions to have enabled on your device.
See page 12 for how to set actions for your sensor.
Select the Done button when completed. 
SETTING UP YOUR CO² SENSOR
When you are finished adding the sensor to your account, the next step is to insert the battery. The type of battery you use will depend on the category of your sensor. ALTA Wireless CO² Sensors are powered by AA batteries.
INSTALLING BATTERIES
ALTA commercial sensors are powered by AA batteries. Monnit encourages
customers to recycle all old batteries.
The standard version of this sensor is powered by two replaceable 1.5 V AA-
sized batteries (included with purchase). The typical battery life is up to 10
years.
This sensor is also available with a line power option.
The line-powered version of this sensor has a barrel power connector allowing
it to be powered by a standard 3.0?3.6 V power supply. The line-powered
version also uses two standard 1.5 V AA batteries as backup for uninterrupted
operation in the event of a line power outage.
Power options must be selected at the time of purchase, as the internal
hardware of the sensor must be changed to support the selected power
requirements.
Place batteries in the device by first taking the sensor and sliding the
battery door open.
Insert fresh AA batteries in the carriage, then shut the battery door.
Complete the process by opening up iMonnit and selecting Sensors from the main
navigation menu. Verify that iMonnit is showing the sensor has a full battery
level. 
ANTENNA ORIENTATION
In order to get the best performance out of your ALTA Wireless Sensors, it is
important to note proper antenna orientation and sensor positioning. Antennas
should all be oriented in the same direction, pointing vertically from the
sensor. If the sensor is mounted flat on its back on a horizontal surface, you
should bend the antenna as close to the sensor housing as possible giving you
the most amount of antenna pointing vertically. You should make the antenna
wire as straight as possible, avoiding any kinks and curving of the wire.
Sensors must be at least 3 ft. away from other sensors and the wireless
gateway to function. 
SENSOR OVERVIEW IN iMONNIT
Select Sensors from the main navigation menu on Monet to access the sensor
overview page and begin making adjustments to your Carbon Dioxide Sensor.
MENU SYSTEM
A. Details – Displays a graph of recent sensor data
B. History – List of all past heartbeats and readings
C. Events – List of all events attached to this sensor
D. Settings – Editable levels for your sensor
E. Calibrate – Set your sensor to read more accurately
F. Scale – Change the scale of readings for your sensor
Directly under the tab bar is an overview of your sensor. This allows you to see the signal strength and the battery level of the selected sensor. A colored dot in the left corner of the sensor icon denotes its status.
- Green indicates the sensor is checking in and within user-defined safe parameters.
- Red indicates the sensor has met or exceeded a user-defined threshold or triggered event.
- Gray indicates that no sensor readings are being recorded, rendering the sensor inactive.
- Yellow indicates that the sensor reading is out of date, due to perhaps a missed heartbeat check-in.
Details View
The Details View will be the first page you see upon selecting which sensor
you would like to modify. 
A. The sensor overview section will be above every page. This will
consistently display the present reading, signal strength, battery level, and
status.
B. The Recent Readings section below the chart shows your most recent
data received by the sensor.
C. This graph charts how the sensor fluctuates throughout a set date
range. To change the date range displayed in the graph, navigate up to the top
of the Readings Chart section on the right-hand corner to change the form
and/or to date.
Readings View
Selecting the Readings Tab within the tab bar allows you to view the sensor’s
data history as time-stamped data.
- On the far right of the Sensor History Data is a cloud icon. ( ) Selecting this icon will export an Excel file for your sensor into your download folder.
Note: Make sure you have the date range for the data you need input in the From and To text boxes. This will be the previous day by default. Only the first 2,500 entries in the selected date range will be exported.
The data file will have the following fields:
MessageID: Unique identifier of the message in our database.
Sensor ID: If multiple sensors are exported, you can distinguish between
the sensors using this number even if the names are the same.
Sensor Name: The name you have given the sensor.
Date: The date the message was transmitted from the sensor.
Value: Data presented with transformations applied, but without
additional labels.
Formatted Value: Data transformed and presented as it is shown in the
monitoring portal.
Raw Data: Raw data is stored from the sensor.
Sensor State: Binary field is represented as an integer containing
information about the state of the sensor when the message was transmitted.
(See Sensor State? explained below.)
Alert Sent: Boolean indicating if this reading triggered a notification
to be sent from the system.
Sensor State
The value presented here is generated from a single byte of stored data.
A byte consists of 8 bits of data that we read as Boolean (True (1) / False
(0) fields.
When broken into individual bits, the State byte contains the following
information: aaaabcde
STS: This value is specific to the sensor profile and is often used to
indicate error states and other sensor conditions.
UNUSED: This sensor does not use these bits.
AWARE: Sensors become aware when critical sensor-specific conditions are
met. Going aware can cause the sensor to trigger and report before the
heartbeat and cause the gateway to forward the data to the server immediately
resulting in near-immediate transmission of the data.
TEST: This bit is active when the sensor is first powered on or reset and
remains active for the first 9 messages when using default configurations.
STS Specific Codes:
0 = No problems, the sensor is functioning normally.
1 = Open circuit detected in lead.
2 = Short circuit detected in lead.
3 = Range error. Temperature is reading outside of -40 F and 257 F (-40 C and
125 C).
If the user has calibrated the sensor, the Calibrate Active field is set to
False (0) and the sensor is operating inside the Min and Max Thresholds, the
bits look like 00000000, this is represented as 0.
If the sensor is using factory calibrations and it is outside the threshold,
the bit values are 00010010 and are represented as 18(16+2 because both the
bit in the 16 value is set and the bit in the 2 value is set).
Settings View
To edit the operational settings for a sensor, choose the Sensor option in the
main navigation menu then select the Settings tab to access the configuration
page.
A. Sensor Name is a unique name you give the sensor to easily identify it
in a list and in any notifications.
B. Heartbeat Interval is how often the sensor communicates with the
gateway while in the Aware State.
C. Aware State Heartbeat is how often the sensor communicates with the
gateway while in the Aware state.
D. The CO2 Instantaneous Threshold is the maximum value the sensor can
read before it goes into an aware state.
E. CO2 Instantaneous Buffer prevents the sensor from bouncing between
standard operation and an Aware State when assessments are very close to a
threshold.
F. CO2 Time Weighted Average Threshold Default value: is 10000 ppm. TWA
CO² values above this level will cause the sensor to become aware.
G. CO2 Time Weighted Average Buffer PPM is a buffer to prevent the sensor
from bouncing that may occur between Standard Operation and Aware State when
assessments are very close to a threshold. The Buffer can be a maximum of 50%
of the Threshold.
H. Measurement Interval Minutes Default value: is 10 minutes. How often
the sensor makes a measurement.
The default heartbeat interval is 120 minutes or two hours. It is recommended
that you do not lower your heartbeat level too much because it will drain the
battery.
Finish by selecting the Save button.
Note: Be sure to select the Save button anytime you make a change to any
of the sensor parameters. All changes made to the sensor settings will be
downloaded to the sensor on the next sensor heartbeat (check-in). Once a
change has been made and saved, you will not be able to edit that sensor’s
configuration again until it has downloaded the new setting.
Calibrate View
If a sensor type has readings that need to be reset, the Calibrate tab will be
available for selection in the sensor tab bar.
To calibrate a sensor, ensure that the environment of the sensor and other
calibration devices are stable.
Enter the actual (accurate) reading from the calibration device into the text
field. If you need to change the unit of measurement you can do that here.
Press Calibrate.
To ensure that the calibration command is received prior to the sensor’s next
check-in, press the control button on the back of the gateway, once, to force
communication (Cellular and Ethernet gateways).
After pressing the “Calibrate” button and choosing the gateway button, the
server will send the command to calibrate the specified sensor to the gateway.
When the sensor checks in, it will send the pre-calibration reading to the
gateway, then receive the calibration command and update its configuration.
When the process is completed, it will send a Calibration Successful? message.
The server will display the sensor’s last pre-calibrated reading for this
check-in, then all future readings from the sensor will be based on the new
calibration setting.
It is important to note that after calibrating the sensor, the sensor reading
returned to the server is based on pre-calibration settings. The new
calibration settings will take effect on the next sensor heartbeat.
Note: If you would like to send the changes to the sensor right away, please remove the battery(s) for a full 60 seconds, then re-insert the battery(s). This forces the communication from the sensor to the gateway and this the message to make a change from the gateway back to the sensor. (If the sensors are industrial sensors, turn the sensor off for a full minute, rather than removing the battery).
Creating a Calibration Certificate
Creating a sensor calibration certificate will mask the calibration tab from
those who should not have permission to adjust these settings. Permissions for
self-certifying a calibration must be enabled in user permissions.
Directly below the calibrate button is the selection to “Create Calibration
Certificate.
A. The Calibration Facility Field will be filled. Select the dropdown
menu to change your facility.
B. The Certificate Valid Until field must be set one day after the data
contained in the “Date Certified” field.
C. “Calibration Number” and “Calibration Type” are unique values to your
certificate.
D. If necessary, you can reset the heartbeat interval here to 10 minutes,
60 minutes, or 120 minutes. By default, this will be set to no change.
E. Choose the “Save” button before moving on.
When the new certificate is accepted, the Calibration tab will change to a
Certificate tab. 
You will still be able to edit the certificate by choosing the Certificate Tab
and navigating down to “Edit Calibration Certificate.”
The tab will revert back to “Calibrate” after the period for the certificate
ends.
Scale View
If the sensor settings are influenced by temperature, the scale option will be
available in the tab bar. To change the temperature unit of measurement from
Fahrenheit to Celsius or vice versa, select the Scale tab.
Choose the text box to trigger a pop-up window allowing you to change the
scale. Select the scale you prefer and push Set.
Press the Save button to complete your adjustment.
Changing units here will also change units on the sensor physical display.
Units changed locally on the sensor itself will not be changed in this setting
in iMonnit.
ACTIONS OVERVIEW
Device notifications can be created, deleted, and edited by selecting the
Actions Tab in the tab bar.
You can toggle the Action Trigger on or off by selecting the switch under

SECURITY
Data security and integrity are paramount at Monnit. Each layer of the system is secured using encryption and protocols designed to protect customer data and information. The system consists of a sensor(s), gateway(s), and iMonnit software. One or more sensors communicate with iMonnit software through a gateway.
SENSOR TO GATEWAY
Sensor and gateway radio modules are purpose-built devices with proprietary
unreadable firmware, which means the sensor cannot be physically hacked or re-
purposed for malicious purposes. This adds a strong level of inherent security
even before considering encryption. Data transmission between the sensor and
gateway are secured using Encrypt-RF Security (Diffie-Hellman Key Exchange +
AES-128 CBC for sensor data messages). Beyond the encryption, data
transmissions are also structurally verified and CRC checked before they are
passed up to iMonnit or down to the sensor, this ensures the integrity of the
data itself.
GATEWAY TO IMONNIT
Data transmissions between the gateway and iMonnit software are secured using
256-bit, bank-level encryption.
Monnet
Access is granted through the iMonnit user interface or an Application
Programming Interface (API) safeguarded by 256-bit Transport Layer Security
(TLS 1.2) encryption. TLS is a blanket of protection to encrypt all data
exchanged between Monet and you. The same encryption is available to you
whether you are a Basic or Premiere user of iMonnit. You can rest assured that
your data is safe with iMonnit.
SENSOR PRINTS
Sensor prints utilize a shared key between the software and the sensor to
ensure that once the data comes to iMonnit it is guaranteed to be from the
device identified by the sensor print. If this feature is purchased for the
device (via iMonnit software) the device’s data becomes impossible to spoof by
any malicious device.
