How does a Multispectral camera agriculture work in order to understand Multispectral camera technology. It is useful to consider first how monochrome and color. Cameras work a monochrome. Camera contains an image sensor which is comprised of a two-dimensional array of light-sensitive pixels. These pixels are sensitive to incoming light across a broad spectral range for example in a monochrome CMOS image sensor. Each pixel is sensitive to light from 400 nanometers to 1,000 nanometers covering visible and NIR ranges a monochrome image sensor captures light at all. Wavelengths and hence cannot discriminate between different colors and wavelengths of light. The images are black and white like a monochrome camera.
A raw image captured with a color camera can be thought of as three separate images which when recombined through a debayering process form a familiar color image. Spectral imaging devices typically employ similar principles for generating Multispectral images. However, patterning pigments representing red and blue colors on the image sensor spectral devices pattern the sensor with micro sized optical filters that have tunable color and transmission characteristics.
This farm telemetry data allow the professional farmers to monitor, plan and manage the farm more effectively saving time and money along with reducing the use of pesticides. In addition to, the benefits of implementing telemetry in farm is to remotely monitor water points on large-scale cattle properties.
In this post, Agrotechnomarket explains the basics of Multispectral imaging technology, reflectance, wavebands and vegetation indices such as NDVI and NDRE. All this information gives the professional farmer terrific insights into the health of the soil, livestock and plants.
We also show you the latest multispectral sensors for drones in farming. Let’s take a look now at some of the latest multispectral imaging remote sensors. There are Sentera, Parrot Sequoia, Tetracam, and many more.

Benefits of Multispectral Imaging Using Drones in Agriculture Sectors
The technology Multispectral images are a very effective tool for evaluating soil productivity and analyzing or detecting plant health both with stations positioned at fixed points in particularly delicate areas, or with mobile devices mounted on unmanned air vehicles (UAVs), commonly known as a drone. Surveying the health of soil, crops and livestocks with drones, you can obtain a high spatial detail of the information, different with the naked eye, you will get very limited information. A Multispectral sensor technology allows the farmer to see further than the naked eye, coupled with the enormous speed acquisition in analysis of the data.
