01 COMPONENTS
Thank you for purchasing a Clarity Node! You’ll find the following components in the box:
Please note that hardware and tools required for mounting the device on a pole, wall or
panel (e.g., Phillips screwdriver, zip ties, or additional screws) are not included as they
depend on the requirements of the deployment site. Additional extension cords and plug
converters may also be needed to power the device.
UV-resistant plastic zip ties or metal zip ties are recommended to securing the device
outdoors. In addition, extension cord protectors can be used to weatherproof the power
connectors for outdoor use.

02 CHOOSING A DEPLOYMENT SITE
Ensure the site satisfies the following requirements:
1. Site has access to 2.4 GHz WiFi connectivity.
2. 6 to 15 feet in height from street level to measure general population exposure and
more than 20 feet away from obvious pollution sources (chimney or exhaust).
3. A pole, wall, or panel available for mounting.
4. A powered outlet available to power the device.
5. Infrastructure should allow air inlet/outlet on the Node to be positioned facing down
towards the ground & unobstructed.
03 DEVICE CONFIGURATION
1. Scan the Node ID on the device using a QR code scanning
application or the camera app on your mobile device to
automatically access the Clarity Deployment Tool.
Alternatively, you may access it at https://deploy.clarity.io.
2. Log in with the credentials provided on the Quick Start
Guide in the box. Please save these credentials.
3. Upon successful login, you will see your device labeled as
unconfigured. If you purchased more than one device, you
will see other Node IDs here.
4. Click on the + sign next to the device you’d like to
configure. A form will appear to configure the device.

5. Fill out the fields in the form and hit “Submit”.
6. A pop-up message will indicate that the device has been configured.
A0000001
Enter location latitude (e.g., “38.0704608”)and longitude
(e.g., “-120.1429285”)or select location on the map
Enter height above ground level (m) e.g., “5”
Enter distance from nearest road (m) e.g., “35”
Optional Upload image of deployed device

04 WIFI CONFIGURATION
1. Plug the device into a power outlet with the provided power adapter. A Power On sound
(See Appendix B for details on sounds), indicating that it is powered on.
2. On a phone or computer, select “Clarity_AP” from available WiFi networks (Figure 3).
3. A menu or browser will pop up (Figure 4). If not, go to 192.168.4.1 in the web browser.
4. If connecting to a new WiFi network, select “Configure WiFi”. Select “Connect Now” if
the saved WiFi network is the desired network to start connecting.
5. Please enter the WiFi SSID and password for the desired WiFi network. Click “Connect to
WiFi” and wait for connection status (Figure 5).
6. If successful, the device will play the Connection Successful sound (See Appendix B for
details on sounds), indicating that it is connected. If unsuccessful, the device will play
the Connection Fail sounds (See Appendix B for details on sounds). Please proceed to
Troubleshooting (Appendix A).

If one cannot upload
data:
1. Ensure the device has
been configured
properly.
2. Ensure there is
internet connection.
