MONNIT AQ-P25A Air Quality PM 2.5 Meter

I. ABOUT THE AIR QUALITY PM 2.5 METER
The ALTA Air Quality PM 2.5 um Meter measures concentrations in the air and transmits the measurement to iMonnit. The Air Quality Meter works by turning on a small fan at the beginning of a measurement cycle to bring in a volume of ambient air and measuring the
particulate matter (PM) content of that sample volume. The meter measures PM content using a laser that scatters based on the number and size of particles suspended in the air. It is important to keep the inlet ports of the sensor clear to ensure proper readings.

II. SENSOR SECURITY

Security is paramount for the sensor when it comes to managing your data and transferring it to sensors. iMonnit is the online software and central hub for configuring your device settings. All data is secured on dedicated servers operating Microsoft SQL Server.

Data Security on the Sensor

The fortified sensor secures your data from attackers and secures the sensor from becoming a relay for malicious programs. Even when the sensor is at rest, the sensor is designed to prevent prying eyes from accessing the data. The sensor does not run on an off-the-shelf multi-function OS (operating system). Instead it runs a purpose-specific real-time embedded state machine that can?t be hacked to run malicious processes. It also provides no active interface listeners that can be used to gain access to the device over the network.

iMONNIT Security

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.

III. 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 follow the steps below to make sure you are performing your set-up correctly.

SET-UP STEPS

1. Register your gateway on iMonnit.
   Your gateway must be registered first to verify communication between the device and iMonnit. Any sensors or meters you wish to add onto your network must come after the gateway.

2. Register your sensor on iMonnit.
   Add your sensor to the iMonnit account (see page 3 for step-by-step directions).
   

3. Connect the Ethernet and optional power cords to the sensor.
   Plug in powered Ethernet cable. Depending on your facility, you might need to plug in both the Ethernet cable and power cord.

4. Mount your sensor.
   Place your sensor in the desired location using screws or double-sided tape.

Note: Each step is covered in more detail in the following sections.

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.
   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.
   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.
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.
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.

V. SENSOR OVERVIEW
Select Sensors from the main navigation menu on iMonnit to access the sensor overview page and begin adjusting your sensors.

MENU SYSTEM
Details – Displays a graph of recent sensor data
History – List of all past heartbeats and readings
Actions – List of all actions attached to this sensor
Settings – Editable levels for your sensor
Calibrate – Reset readings for your sensor
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 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 is within user-defined safe parameters.
• Red indicates the sensor has met or exceeded a user-defined threshold ortriggered event.
• Gray indicates that no sensor readings are being recorded, rendering the sensor inactive.
• Yellow indicates that the sensor reading is out of date, possibly due to 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 is at the top of 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. The Readings Chart displays 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 “From:” 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 as it is stored from the sensor.
Sensor State: Binary field represented as an integer containing information about the state or 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 integer 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.
Using a temperature sensor as an example:
If the sensor is using factory calibrations, the Calibrate Active field is set True (1) so the bit values are 00010000 and it is represented as 16.
If the sensor is outside the Min or Max Threshold, the Aware State is set True (1) so the bit values are 00000010 and it is represented as 2.
If the user has calibrated the sensor, the Calibrate Active field is set 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 it is 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 and 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 along with any notifications.
• B. Heartbeat Interval: is how often the sensor communicates with the server if no activity is recorded. The default heartbeat interval is 120 minutes or two hours.
• C. Aware State Heartbeat: is how often the sensor communicates with the server 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. PM 2.5 Threshold: is the maximum threshold for air particulate readings. Data above this threshold will send the meter into an aware state.
• F. PM 10 Threshold: the maximum threshold for air particulate 10 readings. Data above this threshold will send the meter into an aware state.
• G. PM 1.0 Threshold: the maximum threshold for air particulate 1.0 readings. Data above this threshold will send the meter into an aware state.
• H. Show full Data Value: Shows the value of your reading.
• 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.

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.
