I. ABOUT THE WIRELESS AIR VELOCITY SENSOR
The ALTA Wireless Air Velocity Sensor measures the pressure difference between two input
ports, the temperature, and altitude determines the speed at which the air is moving in a
system and transmits the measurement to iMonnit.
PAGE 1

EXAMPLE APPLICATIONS
- Building/Room Pressure
- Air Flow
- Variable Air Volume Filter Status
- Duct Pressure
- Clean Rooms
- Hospitals
- Fume Hoods
- Computer Rooms
- Additional applications
- Measurement range: -50 m/s to 50 m/s
- Calibrated and temperature compensated
The sensor measures the pressure difference between two ports. When viewing the sensor
from the top, the right inlet port is the positive or high side pressure input. When the
pressure on this port is greater than the left port the sensor produces a negative pressure
reading. When the pressure is greater on the left port the sensor produces a positive
pressure reading. Combined with the temperature and the altitude, the sensor determines
at what rate the air is flowing in a system.

II. 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.
1. Create iMonnit Account (If new user).
2. Register all sensors and gateways to a network in iMonnit.
Sensors can only communicate with gateways on the same iMonnit
network.
3. Connect/power on gateway and wait till it checks into iMonnit.
4. Power on sensor and verify it checks into iMonnit.
We recommend powering the sensor on near the gateway then moving to the
installation location, checking signal strength along the way.
5. Configure sensor for use (This can be done at any point after step 2)
6. Install sensor in final location.
Note: Device specific setup is covered in more detail in the following
sections.
Note: For information on setting up iMonnit and the gateway refer to
the iMonnit User Guide and the gateways user guide.

III. 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
1. Add the sensor on iMonnit.
Add the sensor to your account by choosing Sensors in the main menu.
Navigate to the Add Sensor button.
2. 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.
3. 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.

Desktop Mobile
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 2: SETUP
Figure 3
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 3: VALIDATION

IV. SETTING UP YOUR AIR VELOCITY 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 Air Velocity Sensors will either be powered by a AA or an industrial battery.
PAGE 5
INSTALLING BATTERIES
ALTA commercial sensors are powered by AA or industrial 3.6V Lithium batteries supplied
from Monnit or another battery supplier. Monnit encourages customers to recycle all old
batteries.
AA 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 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 line power outage.
Power options must be selected at 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.
Industrial Batteries
3.6V Lithium batteries for the Industrial Wireless Air
Velocity Sensor is supplied by Monnit. The ALTA
battery life for the Industrial battery is up to 7 years.
Industrial batteries should not be removed from the
device or replaced.
In order for the sensor to function properly, you will
need to attach the included antenna. Simply screw the
antenna onto the barrel connector on the top of the
device. Make sure the antenna connection is snug, but
Figure 6
Figure 7
Figure 8
Since the electronics are sealed within the sensor housing, we have added an "On/Off"
switch to the unit for your convenience. If you are not using the sensor, simply leave the
button in the off position to preserve battery life. If the sensor needs to be reset for any
reason, you can simply cycle the power by turning the switch to the "Off" position and
waiting 30 seconds before powering back on.
MOUNTING THE SENSOR
Monnit wireless sensors feature mounting flanges and can be attached to most surfaces
using the included mounting screws or double-sided tape.
PAGE 6
do not over tighten. When placing the sensor, make sure to mount the sensor with the
antenna oriented straight up (vertical) to ensure the best wireless radio signal.
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 vertical. 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.

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.
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 as it is stored from the sensor.
Sensor State: Binary field 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, 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).
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.

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 the 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 if no activity is
recorded.
C. Aware State Heartbeat is how often the
sensor communicates with the gateway while in
an Aware State.
D. Assessments Per Heartbeat is how many
times between heartbeats a sensor will check its
measurements against its thresholds to
determine whether it will enter the Aware State.
E. Below is the lowest allowable value for the
sensor.
F. Above is the highest allowable value for the
sensor.
G. Aware State Buffer is a buffer to prevent the
sensor from bouncing between Standard
Operation and Aware State when the
assessments are very close to a threshold.
H. Altitude is the set altitude of the sensor.
I. Show Temperature shows the temperature
with an air pressure reading.
J. Synchronize is a setting that in small sensor
networks synchronizes communication. The
default setting OFF allows the sensors to
randomize their communications therefore
maximizing communication robustness. Setting
this will synchronize the communication of the
sensors.
K. Failed transmissions before link mode is the number of transmissions the sensor
sends without response from a gateway before it goes to battery saving link mode. In link
mode, the sensor will scan for a new gateway and if not found will enter battery saving
sleep mode for up to 60 minutes before trying to scan again. Lower numbers will allow
sensors to find new gateways with fewer missed readings. Higher numbers will enable the
sensor to remain with its current gateway in a noisy RF environment better (Zero will cause
the sensor to never join another gateway to find a new gateway, the battery will have to be
cycled out of the sensor.)
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).

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.
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.

VII. SECURITY
Data security and integrity is 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 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.
iMONNIT
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 iMonnit
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 devices data
becomes impossible to spoof by any malicious device.
