SEQUOIA PRESENTATION
Sequoia is a multispectral sensor specifically for farming. It is designed
according to three main criteria: outstanding precision, minimum size
and weight and ease of use. The Sequoia sensor is designed to be
suitable for all types of drones, those with fixed wings as well as multi-
rotors and mounted on gimbals or not. It can be used to take pictures
of agricultural fields in several spectral bands which measure the state
of the vegetation: Green (550nm wavelength, 40nm bandwidth), Red
(660nm wavelength, 40nm bandwidth), Red Edge (735nm wavelength,
10nm bandwidth) and Near Infrared (790nm wavelength, 40nm
bandwidth).
The photos taken can then be analysed using various software. They
can be used to make indexed maps (NDVI, NDRE, etc.) and make
recommendations regarding nitrogen fertilisation.

Sunshine sensor
The sunshine sensor is used to calibrate the images depending on the
sunlight. This makes it possible to compare photos over time, despite
variations in light during photo shoots. The sunshine sensor is attached
on the upper part of the drone, facing the sky. During flights the
sunshine sensor is powered by the multispectral sensor.
!It is recommended to use a TS32GSDU3X SD card with
Sequoia. Performances are not guaranteed for other SD cards.
Check SD card compatibilities on www.parrot.com/entreprises/

There are three different holders for attaching the sunshine sensor to the
drone.
•Flat bottom holder to attach the sunshine sensor to a flat surface.
•Concave bottom holder to attach the sunshine sensor to a rounded
surface.
•Pivoted holder to attach the sunshine sensor to a rounded surface.

CONFIGURING SEQUOIA
You can set up Sequoia using either flight planning software (such as
Pix4Dmapper Capture or eMotion from SenseFly for example), or Wi-Fi
via an HTML interface. Your set up data will be saved in the Sequoia
memory.
Setting up Sequoia via Wi-Fi
Wi-Fi is enabled on Sequoia as the default option. Press four times on
the multispectral sensor button to enable/disable Wi-Fi on Sequoia.
Subsequently, Sequoia keeps the last Wi-Fi set up in its memory, when
it is switched on or off.
You can set up Sequoia from a computer, smartphone or tablet:
1. Connect the multispectral sensor USB device port to a drone or a
USB battery.
>Sequoia turns on automatically.
2. Make sure that the Wi-Fi appears in the list of available Wi-Fi. If not,
press four times on the multispectral sensor button.
3. Connect to the Wi-Fi network: Sequoia_XXXX.
4. Open your internet browser
5. Type the following address in your browser's address bar:
192.168.47.1
>The HTML interface for setting up Sequoia opens. You can set
up Sequoia.
HTML interface for setting up Sequoia
The Sequoia set up interface consists of three screens:
•Home
•Status
•Gallery

Home
The Home screen is used to set up Sequoia.
Setting up the capture mode
Select the capture mode you want:
•Single: take one shot at a time.
•Time-lapse: take burst shots at regular intervals. Specify, in the
"time-lapse" field, the interval of time (in seconds) between each
shot.
•GPS: take burst shots at regular distances. Specify, in the "GPS"
field, the distance in metres between each photo.
Once the set up is complete, press the Shot button. The camera starts
taking shots. To stop taking shots, press the Stop shot button.
To automatically calculate your settings press .

•Sequoia's altitude in meters.
Instruments
The Instruments screen tells you about the orientation of the
multispectral sensor and the sunshine sensor.
Irradiance
The Irradiance screen tells you about the light intensity of each band
(Green, Red, Red Edge, Near Infrared).
Temperature
The Temperature screen tells you about the temperature of all
Sequoia's parts.
Gallery
The Gallery screen can be used to retrieve the photos taken during your
flights. You can select the photos that you would like to view (All, RGB,
Green, Red, Red Edge and Near Infrared).

17
ENGLISH
You can view photos in the Sequoia's internal memory or on the SD
card.
Gallery tells you how much space is available in the Sequoia's internal
memory and on the SD card.
Settings
•Edit the Sequoia's Wi-Fi name, and enable/disable the Wi-Fi.
•Use the "Force calibration" button to recalibrate Sequoia.
•Use the "Update Sequoia" button to update Sequoia.
•Use the "Restore to factory settings" button to restore the Sequoia
to factory settings.
CHECKS TO BE MADE BEFORE USE
Before each flight with Sequoia, make the following checks:
•Make sure that the lenses are clean. Use the microfibre cloth (sup-
plied) to clean them.
•Free up enough memory (either in the multispectral sensor internal
memory, or on your SD card) so you can save all the photos taken
during the flight.
•Make sure that the two modules are properly attached to the drone
and that they are not likely to come off during the flight.
•Make sure that the micro USB device cable which connects the
drone to the multispectral sensor is connected.
•Make sure that the two sensors are calibrated. For more informa-
tion, see the Calibrating Sequoia section.
•Wait until the sunshine sensor indicator light is green. When it is
green this means that the GPS/GNSS is enabled.

USING SEQUOIA
Note: If Sequoia detects an SD card the shots are saved on this
SD card. If no SD card is detected, Sequoia automatically saves
the shots in its internal memory.
Remove the protective lens cover
Use the protective lens cover before using Sequoia.
The protective lens cover is used for transportation it has to be removed
before use.
Attaching Sequoia to a drone
Sequoia can be attached to all types of drones.
1. Select the sunshine sensor holder which is most suitable for your
drone.
2. Remove the plastic film from the holder and stick the holder on the
back of the drone.
!The holder must be positioned parallel to the drone (diagram
A).
Diagram A
3. Insert the sunshine sensor in its holder.
!To avoid distorting the data the sunshine sensor must not be
covered during photo shoots.
4. Insert the multispectral sensor under the drone, in the kit provided
for this purpose.
5. Connect the multispectral sensor to the sunshine sensor using the
USB host cable.
6. Connect the multispectral sensor to the drone using the USB
device cable.
>Sequoia turns on automatically (Diagram B).

ENGLISH
Diagram B
!Make sure that the Sequoia cables do not get caught in the
drone propellers during the flight.
Connecting Sequoia to a USB battery
You can use Sequoia without a drone. To do this, you need a 2,4A USB
battery at least.
1. Connect the multispectral sensor to the sunshine sensor using the
USB host cable.
2. Connect the multispectral sensor to the battery using the USB
device cable.
>Sequoia turns on automatically (Diagram C).
Diagram C
Calibrating Sequoia
Before using Sequoia, you must calibrate it. Before starting the
calibration, make sure that the two sensors are properly attached and
connected to the drone.
!The multispectral sensor and the sunshine sensor must be
attached perpendicularly. It is recommended to calibrate the
two sensors at the same time.
Note: You can calibrate the sensors separately. However the
sunshine sensor must be connected to the multispectral sensor
to be calibrated.
