In today's market, every bushel count and flying toys won't cut it. With the Parrot Sequoia+, the consumer drone is what all you need. With its mini-camera format and light weight, Sequoia multispectral sensor adapts to all drones, both multi-rotor and fixed wing. It has quickly become one of the most sought-after cameras.
Including its unique features, it is the perfect combination of technology, mobility and affordability that allows you to keep track of your crop’s health. With its two sensors, multispectral and sunshine, Parrot Sequoia analyses plants vitality, help you find problems in your field, control irrigation, estimate crop productivity, optimize pesticide input and refine fertilization.
Sequoia is certainly the smallest and lightest sensor and is a groundbreaking sensor in an amazing little bundle.
Let’s start from calibrating our Parrot Sequoia! First, make sure the sensors are properly attached and connected. Then, we can start the calibration.
The multispectral sensor must be perpendicular to the sunshine sensor. It is best to calibrate them both at the same time.
Note: If calibrating separately, the sunshine sensor must be connected to the multispectral sensor.
Step 1: Check that the Sequoia indicator light flashes purple.
Step 2: Make sure to rotate the drone on the Z-axis (yaw axis) until the green indicator light flashes on the sensor
Step 3: Rotate the drone on the Y-axis (pitch axis) until the blue indicator light flashes on the sensor.
Step 4: Rotate the drone on the x-axis (roll axis)until the indicator changes color.
Note: Once it’s completely finished, the sensor light will vary depending on the status. For instance, if the memory is full, the light indicator will flash yellow.
How to mount the Sequoia+ to a drone?
The Parrot Sequoia camera can be easily connected; using either a fixed or gimbaled mount on your drone.
What spectral bands does the Sequoia camera capture?
Sequoia captures 4 discrete spectral bands: Green, Red, Red Edge and Near Infrared, and 3 non-discrete spectral bands (as part of the RGB imagery).
Do I still need to take panel shots if I am using a sunshine sensor?
Yes. An image of the calibrated reflectance panel is still needed both before and after flight to confirm the calibrations of the camera and the sunshine sensor or Downwelling Light Sensor (DLS). When performing the panel capture, ensure that both the panel and the sensor are being exposed to direct light from the sky, without shadowing and without reflections from other objects. In the future, there'll be an improve processing such that the panel shots are no longer needed when using the DLS or sunshine sensor.
How setup is achieved and is it required?
Yes, it is necessary to setup the Sequoia with the included software. To setup Sequoia, you need to uses a computer, smartphone or tablet to run the software and sync with the drone. Also, because of the on board IMU, you'll have to perform a handheld compass configuration which takes less than a minute.
What is the definition of the images captured by Parrot Sequoia+?
Each monochrome sensor has a 1.2 MP resolution in synchronized narrow-band. Each image is 1280x960 pixels. In addition, the RGB camera captures 16MP with a resolution of 4608x3456 pixels.
Does the Sequoia have built-in storage?
Can Parrot Sequoia be used with any drone?
Yes, you can use Sequoia with any drones due to its compact size which fits easily. The biggest highlight as well, it includes those with both fixed wing and multi-rotor functionality.

Focal length: 4.88 mm
How Sequoia Sunshine (Irradiance) Sensor work?
In the event that the power of the ambient light differs, the measure of the crops, reflected light vitality will be adjusted and the outcome of the processed data will be distorted. Sequoia integrates a second sensor, known as the Sunshine Sensor, to adapt to light fluctuation, which is mounted on the top of the drone. This will record the light conditions in the same spectral bands during the flight. With its inclusions, it allows to be utilized in a clear as well as in cloudy condition, along these lines improving adaptability of usage.
How to change Parrot Sequoia's settings?
You can configure Parrot Sequoia+ using a flight planning software (e.g. Pix4Dmapper Capture or eMotion from SenseFly) or Wi-Fi via an HTML interface. Your settings will be saved in Parrot Sequoia's memory.
Is Parrot Sequoia+ compatible with E-motion?
Yes, Parrot Sequoia+ is fully compatible with e-Motion.
What is the format of the data produced?
The data is saved in the internal memory of the sensor or on an SD card. They are in the following format:
RAW 10-bit TIFF file for the four monochrome sensors.
JPG format file for the RGB sensor.
How big are the two units?
They’re surprisingly small for such sophisticated instruments. Sequoia: 2.3 x 1.6 x 1.1 inches; sunshine sensor: 1.8 x1.5 x 0.7 inches.
I looked around other online stores, but chose UAVPrime. Glad I did. They had me flying by the end of the week!
I called in over the phone and was amazed at the service. They took real good care of me.
After being let down by another store, I found UAVPrime. Andrew was helpful and got me on the right track!
