Connecting to Sentera 6X Thermal Pro via Webpage

You have the ability to connect to the Sentera 6X Thermal Pro sensor via a webpage. These are the steps to do so...
Power on the sensor by either:
Using the AC power adapter; or
Installing the sensor onto the aircraft via the Skyport and turning on the aircraft
The wait for the LEDs on the sensor to do either of the following:
Power Method
LED Behavior
AC Power Adapter
Flashing Red
Drone Power
Solid Green (requires GPS Fix)
Solid Red (After 2 minutes w/o GPS)

Connect the sensor to the computer using a USB cable.*
*Use the USB-C port on the side of the sensor not the USB-C port on the top of the gimbal.
*Use the USB-C Cable provided with the 6X for the best and most reliable performace
Open a web browser and enter
A home page should appear similar to:

info
If the webpage can't be connected to after a few minutes try the following:
Verify the sensor has had around a minute to boot.
Turn off/disconnect any Wi-Fi or Ethernet connections that have internet access.
Verify the USB cable being used is the provided cable or one of the listed .
If the 6X is being powered with the AC power adapter, the No Gimbal Communication application will appear. This is expected as the gimbal itself is now powered.

Configuration of the Sentera 6X Thermal Pro

For the Sentera 6X Thermal Pro, all configurations should be preset already but in the event that the settings need to be reconfigured there is one setting that needs to be set from the defaults. Below is how to change the Config File to DJI Skyport:

Configuration File

If the Config File is not already set to DJI Skyport this will need to be changed. To do so, click the [change] button beside the currently selected config file

Ensure “All platform configurations” are selected in the Show options and then navigate to the correct config file (GimballedDJI Skyport)

Once selected, click apply & restart.
The sensor will perform a system restart to install the config file
Verify the correct configuration is showing

Work Flow

This is the start to finish workflow for using the Sentera 6X Thermal Pro with the DJI M300 for a mapping mission

Equipment List

Sentera 6X Thermal Pro
GPS & Light Sensor
Calibrated Reflectance Panel (CRP)
Mounting Hardware
GPS & Light Sensor Mount
4 x M3x5mm Phillips Head Screws
Zipties (for cable securement)
Flush cutters (for Zipties
USB C to C Cable
2.5mm Phillips Head Screwdriver

Mounting Rededge-P Dual System

Setup DJI M300
Attach Sentera 6X Thermal Pro to the Skyport attachment on the DJI M300
Mount the GPS/ Light sensor to the top of the M300 (Ensure the orientation of the GPS/Light sensor is installed as shown below)

Connect the GPS/Light Sensor to the USB C port on the Skyport of the Sentera 6X
Once both the Sentera 6X thermal pro sensor & GPS/Light Sensor are installed the completed instillation should look like this:

Turn on the aircraft. Once the 6X LEDs have turned green, move onto capturing the calibrated reflectance panel.

Flying the Mission

When mission planning, ensure you are following the as prescribed below and if the Sentera 6X is not an added sensor in DJI Pilot 2 to refer to
Before actually flying, the first step is to take a picture of the calibrated reflectance panel (CRP). This is done by holding the sensor/ aircraft and pressing the button on the GPS/Light Sensor.
When you are capturing the image of the CRP best practice include:
Hold the sensor/ aircraft 1 meter (or about waist height) over the CRP
Avoid shadowing the panel
Keep the sun at your side
There should be audible beeps form the 6X and the LEDs will flash in this sequence: blinking green, then white, then Turing solid green. If you hear those that means the images were captured.
Once the images are captured, you are ready to fly the mission.

Data Offload Process

To offload the data you will need to connect to the Sentera 6X and copy the data off of the internal SSD. Imagery is NOT store on the micro SD card. The micro SD card holds the configuration settings. Here are the steps to offload the data:
Power on the sensor by using the AC adapter
Connect the sendto to the computer using the USB-C cable
Ensure this is plugged into the side of the sensor and NOT the USB-C on the top of the gimbal
Open a File Browser (PC)/ Finder (Mac)
PC:
In File Browser, Navigate to internal storage by typing \\192.168.42.1 into the address bar of the file browser and pressing enter
Windows will display a network credits pop-up. The username is sentera and there is no password. Press OK
From there to navigate to the data select Data Snapshots → Your desired folder
Copy all of the data
Mac:
In Finder, navigate to internal storage by first going to Network in Finder.
Then there should be a device called SENTERA-6X, select it.
From there to navigate to the data select Data Snapshots → Your desired folder
Copy all of the data.

Flight Settings

When creating a flight plan it's important to follow the recommended flight setting from Sentera to properly capture imagery from the Sentera 6X. Below are recommended settings/ conditions when creating a flight plan:

Orthomosaic

Capture Performance

The Camera Parameters for the Sentera 6X has the capture rate at 1 second intervals. With this, we also need to consider the Capture Rate vs Altitude with Constant Speed & Capture Rate vs Flight Speed with Constant altitude graphs by Sentera when making our flight plans. Below are links to both graphs. Take a look at them before finalizing a flight plan

Environmental Considerations

Time of Day: Flying mid-day when the sun is highest (Solar Noon) is optimal to reduce shadowing effects
Cloud Cover: Flying in uniform lighting conditions is optimal for the 6X. Either mostly clear or completely overcast
Precipitation: Flying in foggy, rainy, or snowy conditions is not advised.

Camera Parameters for DJI Pilot 2

When using a DJI Pilot 2, you may need to create a "custom camera" to enable the app to properly calculate flight paths.
