ABOUT THE WIRELESS DIFFERENTIAL AIR PRESSURE SENSOR
The ALTA Wireless Differential Pressure Sensor measures the pressure difference between two input ports and transmits the measurement to iMonnit.
- Measurement range: -500 Pa to 500 Pa
- Calibrated and temperature compensated
The differential pressure 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.

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 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 set up 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
The sensor is 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 ound 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 phone or 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 DIFFERENTIAL AIR PRESSURE 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 Differential Air Pressure Sensors will either be
powered by commercial AA or an industrial battery.
INSTALLING BATTERIES
ALTA commercial sensors are powered by AA batteries. Industrial sensors need a
3.6V Lithium battery supplied from Monnit or another industrial 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 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.
Industrial Batteries
3.6V Lithium batteries for the Industrial Wireless Differential Air Pressure
Sensor are supplied by Monnit. The ALTA battery life for the Industrial
battery is up to 7 years.
The Industrial sensor does not need to have batteries installed. The batteries
are already in the sensors when they are shipped.
Open iMonnit and select Sensors from the main navigation menu. Verify that
iMonnit is showing the sensor has a full battery level.
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 do not overtighten. When placing
the sensor, make sure to mount the sensor with the antenna oriented straight
up (vertical) to ensure the best wireless radio signal.
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.
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 iMonnit to access the sensor
overview page and begin making adjustments to your Tilt Sensor.
MENU SYSTEM
A. Details – Displays a graph of recent sensor data
B. History – List of all past heartbeats and readings
C. Actions – List of all actions attached to this sensor
D. Settings – Editable levels for your sensor
E. 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 thereshold or triggered event.
- Gray indicates that no sensor readings are being recorded, rendering the sensor inactive.
- Yellow i ndicates 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 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 air pressure level measured in pascals.
F. Above is the highest allowable level measured in pascals.
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. Show Temperature is a switch that shows the temperature with a
pressure reading when switched on.
I. 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.
J. Failed transmissions before link mode is the number of transmissions
the sensor sends without a 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.)
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.
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.

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 is 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 device’s data becomes impossible to spoof by
any malicious device.
