ABOUT THE WATER DETECT PLUS SENSOR

The Water Detect Plus Sensor detects either the presence or absence of water.
For example a leak-prone pipe within a facility. You may want to know when there is no water present, or you may need to know when the pipe begins leaking so it can be quickly repaired. This flexibility makes Monnit’s Water Detect Sensor the best way to monitor water presence in your environment. The sensor will remotely assess and regularly report on activity, instantly notifying you the moment change is detected.

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?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.

Monnet 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 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.

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 to 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.

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

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
   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 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.
To get you up and running fast, your sensor comes with preset use cases. Choose from the list or create your own custom settings. You will see the heartbeat interval, and aware state settings (see page 9 for definitions).
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 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 Water Detect sensors will either be powered by a commercial coin cell, AA, or an industrial battery.

INSTALLING BATTERIES

ALTA commercial sensors are powered by AA or CR2032 coin cell 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.

Coin Cell
The lifespan of a standard CR2032 coin cell battery in an ALTA Water Detect Sensor is 2 years.
Install a coin cell battery by first taking the sensor and pinching the sides of the enclosure. Gently pull up the enclosure, separating the sensor from its base.
Then slide a new CR2032 coin cell battery with the positive side facing toward the base. Press the enclosure back together; you’ll hear a small click.
Lastly, open iMonnit and select Sensors from the navigation menu. Verify that iMonnit is showing the sensor has a full battery level.

AA Batteries
The standard version of this sensor is powered by two replaceable 1.5V AA 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 3.0-3.6V power supply. The line-powered version also uses two standard 1.5V 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
Water Detect Sensor is supplied by Monnit. The ALTA battery life for the Industrial battery is 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.

SENSOR OVERVIEW

Select Sensors from the main navigation menu on Monet to access the sensor overview page and begin adjusting your sensor.

MENU SYSTEM

Details – Displays a graph of recent sensor data
History – List of past readings
Actions – List of 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 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, 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. See Figure 7.
A. The Sensor Overview section is at the top of every page. This will 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 readings fluctuate throughout a set date range. To change the date range displayed in the graph, navigate up to the top of the Readings Chart section in 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 is stored from the sensor.
Sensor State: Binary field is 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 to 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. See Figure 12.

A. Sensor Name is a unique name you give the sensor to easily identify it in a list along with any notifications.
B. The Heartbeat Interval is how often the sensor communicates with the server if no activity is recorded.
C. Aware State Heartbeat is how often the sensor communicates with the server while in an Aware State.
D. Enter Aware State When Water Is field allows you to set whether you want to be alerted when water is either Present, Absent, or when there is a State Change.
E. Time to Rearm is the time in seconds after a triggering event that the sensor will wait before re-arming itself.
F. In small sensor networks, the sensors can be set to synchronize their communications.
The default setting?Off? allows the sensors to randomize their communications, maximizing communication robustness. Setting this will synchronize the communication of the sensors.

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.

ACTIONS OVERVIEW
