Introduction
Kaiterra enterprise air quality monitors are designed to be intuitive solutions for your
continuous air quality monitoring needs.
These monitors can be used in the following cases:
To gain a better understanding of the air quality in your building
To ensure optimized air quality and occupant comfort
To address concerns of occupants and tenants
To analyze how cleaning chemicals impact air quality
To troubleshoot pollution hot spots and identify under-utilized areas
To evaluate the performance of the filtration and HVAC systems
This guide will assist you in determining the best place to install your Kaiterra Sensedge air
quality monitors for individual rooms, large open spaces, and entire building projects.
This guide will also cover power considerations, network considerations, and device
configuration so you are best prepared to handle your upcoming installation project.

*Our guidelines follow the standards outlined in RESET and WELL v2 for sensor area coverage.

For any of Kaiterra’s enterprise air quality monitors, we recommend an area coverage of
3,500ft² (325m²) with the area of each enclosed space calculated individually*.

Page 4
For example:
One (1) open space of 3,500ft² (325m²) requires one (1) monitor
Three (3) conference rooms of 225ft² (21m²) requires one (1) monitor in each room
Spaces over 3,500ft² (325m²) should consider installing multiple monitors throughout the
room to achieve optimal coverage. It is also recommended to align the sensor deployment
areas with the HVAC thermal zoning plan.
This inclusion of multiple sensors in larger spaces is required for achieving various building
certifications, so be sure to check the requirements for your desired certification in order to
meet their standards.
For projects that are not looking to get certified, you have much more flexibility in terms of
what your goals are with IAQ monitoring and the budget available for the project. Feel free to
contact your account representative at Kaiterra to discuss this further.
The following is a sample floor plan that demonstrates how our air quality monitors should be
distributed throughout a typical building floor plan.

Placement Guidelines
For placement, we recommend the guidelines required for RESET Air certification, which
requires RESET Air Accredited Monitors to be installed according to the following
requirements:
A. Wall-mounted and centrally-located within monitored spaces.
B. Mounted in the breathing zone: between 3-6 feet (0.9-1.8 meters) from the ground
(after finished floor to underside of finished ceiling)*.
C. Located at least 16 feet (~5 meters) away from operable windows. In areas where this
is not possible, monitors must be located no closer to windows than half the width of
the space, measured linearly from the windows inwards.
D. Located at least 16 feet (~5 meters) away from air filters and diffusers. In areas where
this is not possible, monitors must be located closer to air returns than air diffusers.

E. Hard-wired to a permanent power source (recommended but not mandatory).
Other things to consider:
Air is drawn into the Sensedge from both the sensor modules on the bottom and the
air intake on the top. It is vital that neither side of the device is covered as any changes
in the airflow may affect the readings and accuracy of our devices.
In order to avoid direct breathing on a device, which would impact your air quality
readings, try to avoid installing air quality monitors right next to a workspace, providing
at least 3 feet (0.9 meters) of space between the device and any workstations. If the
space does not allow this, then make sure the monitor is facing the occupants back.
Our air quality monitors were designed to be installed in an upright position. Please do
not install our products sideways or upsidedown, as your readings will be impacted.
Ceiling installations are also not ideal. If you are going to proceed with a ceiling
installation, please keep in mind the following:
Since your ceilings are likely above the breathing zone, your devices will be
measuring the air that is not directly associated with the air that your tenants,
colleagues, or customers are breathing in, making your readings less accurate
according to the actual air that would impact these individuals.
Temperature and Relative Humidity readings will especially be influenced: as hot
air rises, the Temperature/Relative Humidity readings can be impacted by
numerous degrees/% compared to the breathing zone levels.
Building certifications, such as WELL, RESET, and LEED, may have their own
requirements for things such as installation height and placement. If this installation is
pursuing any of these certifications, please make sure to check their requirements so
that your air quality monitor is properly installed to their specifications.
Exact room placement may vary based on the type of space, but these spaces can be
categorized into two general scenarios:
1. Enclosed Spaces
2. Open Spaces

Page 8
Enclosed Spaces
Definition: A room enclosed by four walls and a door, which is smaller than 3,500ft².
Image 3. A 2,500ft² (232m²) room with three (3) suggested AQM installation locations.

Page 9
Image 3 is an example of an enclosed space with three (3) suggested installation locations.
Assuming that all three locations fall within the breathing zone of 3-6 feet (0.9-1.8 meters),
all three of these locations are acceptable. However:
Location one (1) has the device installed on the same wall as a door. While this is not
a bad thing in this example, as the door is more than 16 feet (~5 meters) away,
smaller rooms might not be able to make this location work as the space between
the device and the door could be smaller.
Because of this, considering installation locations that are separate from any
doors may be easier to ensure ideal conditions -- but for this example, location
one (1) is acceptable.
Kaiterra air quality monitors should be as central to the room as possible. Because of
this, location two (2) is not ideal. However, since the door on the right is 40 feet (12
meters) away, the installer could shift location two (2) toward the center of the
room to become a better option.
Of the three suggested locations, position three (3) is the most ideal since it is
relatively centralized to the room, does not have any features in the way that might
impact air quality, such as windows or diffusers nearby, will provide great coverage
of the regularly occupied space, and would still be ideal if the room was smaller or
narrower.

Page 10
As a comparison, the same example now has a diffuser and a window added to the layout.
Given the RESET placement requirements and Kaiterra’s best practices, the only acceptable
air quality monitor placement for this scenario is position three (3):
It is centrally located -- especially for the regularly occupied space in the room
It is at least three (3) feet (0.9 meters) away from occupants and workstations
It is at least 16 feet (~5 meters) away from any operable windows or diffusers

Open Spaces
Definition: An open space, uninterrupted by walls for more than 3,500ft².
For open spaces, the best way to approach this is to take a look at the entire space as a
whole and determine two key things:
1. How big is the space you are trying to collect data from?
2. What is the optimal placement that will provide the best coverage?
One way of achieving this is to look at a floor plan for the space in question, which will provide
a holistic view of the walls, general placement of furniture, and areas that people will
regularly occupy.
From there, using our recommendation of 3,500ft² (325m²), measure out the larger open
areas of the floor plan, prioritizing the areas that will have regular occupants, such as
workstations, break areas, and receptions.
Since these spaces are larger than 3,500ft² (325m²), divide the space into sections and try
to place a monitor in each section.
Placement should also be aligned with HVAC thermal zones and follow the same, general
rules as enclosed spaces, including avoiding installation locations:
Within 16 feet (~5 meters) of operable windows, doors, air filters, and air diffusers
Within 3 feet (0.9 meters) of occupants and workstations

Page 12
For the example above (Image 5), we have a 10,000ft² (929m²) open space. In order to
achieve optimal coverage for this space, you will want three (3) air quality monitors installed
-- which would meet both WELL and RESET certification requirements.
Since the space has three (3) general sections that will be regularly occupied, the priority
areas would be the top-left, top-right, and bottom-right, which, given the 10,000ft² (929m²)
of the entire space, can be divided evenly for optimal coverage using the suggested monitor
placements.

with three (3) AQMs installed for optimal air data coverage.

Page 13
For non-certification projects with a similar scenario as above, you will still want to prioritize
the regularly occupied spaces. However, you could reduce the number of monitors in the
space from three (3) to two (2) by removing the bottom monitor as this would still provide
great coverage of the regularly occupied areas.

*Note: using third-party power adapters have not been regulated or tested for long term use.
Please use caution when deciding on using any type of power converter with a Kaiterra product.

Power Considerations
Depending on the enterprise air quality monitor you choose for your installation, you will
need to have access to varying types of power in order to properly power your device(s).
The Sensedge natively supports 100-240V AC via USB cable and adapter.
For third-party power options*, you can
use a:
DC 12V-5V USB converter
≥2A 5V Power over Ethernet
splitter
Other things to note:
The USB cable length is 6 feet (2
meters). This is the optimal length
for the USB cable as any longer
runs the risk of not sufficiently
powering the device.
If a third-party USB cable is used,
the cable should be rated at 2.4A
to ensure sufficient power is
carried from the power adapter to the device.
The wall plug adapter converts AC power to DC 5V at 1.8A, which is the required
amount of power for the device.

Network Connectivity and Data Considerations
Network connectivity and data considerations are essential to consider prior to any
installation.
Our Kaiterra Sensedge supports the following:
BACnet/IP via Wi-Fi or Ethernet
Modbus TCP/IP via Wi-Fi or Ethernet
Primary MQTT via Wi-Fi or Ethernet
Secondary MQTT via Wi-Fi or Ethernet
Open API via Wi-Fi or Ethernet via the Kaiterra Cloud
Some network connections may require additional wiring, such as a recommended Ethernet
cable connection. We do not provide any additional wiring with our devices, so if you wish to
use any of the communication protocols above, please make sure you are able to properly
connect to them and provide any necessary wiring.
For more information, please refer to the following documentation:
Sensedge BACnet User Manual
Sensedge Modbus User Manual
Secondary MQTT Documentation
API Documentation

*Note: Inside Mainland China only.
Page 16
While multiple communications can be connected to simultaneously, we recommend, as a
minimum, establishing either a Wi-Fi or Ethernet connection to the Internet. This will allow
your data to be uploaded to the Kaiterra Cloud and Dashboard for ease of access via Primary
MQTT and also enables many other communications and features that require the Internet,
such as our Open API and the Kaiterra Dashboard.
If you plan on connecting your device(s) to the Internet, here are all of the servers and ports
that the device(s) need to access:
MQTT server:
mqtt.kaiterra.com port 8884
mqtt.kaiterra.cn port 8884*
API server:
api.kaiterra.com port 443
api.kaiterra.cn port 443*
Firmware download:
dl.kaiterra.com port 80
dl.kaiterra.cn port 80*
NTP server:
time.kaiterra.com port 123
time.kaiterra.cn port 123*
The MQTT server allows data to communicate with our Kaiterra Cloud and Dashboard.
The API server allows communication between the device and our API.
The Firmware download server allows your device to regularly check for firmware updates.
The NTP server checks to make sure your device maintains an accurate time, preventing
data errors.

Page 17
If it is required to whitelist the MAC address of your device for Internet network access, the
MAC address for the Sensedge can be discovered by navigating to Settings →
WiFi/Ethernet depending on which connectivity you are using.
While Internet Network connectivity is recommended, our Kaiterra Air Quality Monitors can
be used in offline settings. For example: BACnet/IP communication can be established via
Ethernet, but the Ethernet connection does not have to connect online. If an offline
communication is used, we do recommend regularly connecting online to check for firmware
updates as they ensure device stability and functionality.
If desired, data from the Sensedge can also be locally retrieved via microSD card, allowing
the device to be used completely offline with no communication protocols. Insert your
microSD card and navigate to Settings → Data Export → Storage to download your data.

Dashboard Setup
The Kaiterra Dashboard allows you to view the data from your Kaiterra air quality monitors.
Go to dashboard.kaiterra.com and create an account. Then, click “Add Device” and use the
Unique Identifier (UDID) of each device to add them to the dashboard.

Page 19
However, for large scale projects, the process of adding each individual device to the
Kaiterra Dashboard can be difficult. As a workaround, you can make use of the Kaiterra Live
Air Phone App, which enables you to add each Sensedge device to the phone app via QR
code and, when you are ready to add all of your devices to the Kaiterra Dashboard, you can
scan the QR code on the dashboard with the phone app and they will add each device
simultaneously.
To accomplish this, please do the following:
Find and download the Kaiterra Live Air app on your smartphone from the app store
On the Sensedge, navigate to Settings → General → Pair Device to display a QR
code
On the app, navigate to Options → Add New Device → Sensedge, scan the QR code
from the Sensedge, and follow the on-screen instructions.
Once you have added all of the Sensedge devices to the Live Air App, open up the
Kaiterra Dashboard, click on “Add Device”, followed by “add via QR code”.
