Buyer Guide-The Best High-end Naer Infrared Drone Sensors

The next agricultural revolution is here: drones equipped with high-tech sensors are becoming the new tool of preference for farmers around the globe.
Although the sector is highly automated today, we all know that agricultural producers (unlike other industries) don’t crave for fancy toys and new gadgets. Being in the field and working hard all day, what you need is technology that helps you get results: increase yields and decrease inputs while effectively preventing pests and crop diseases.
Like any innovative technology in the traditional agricultural sector, drones are taking their time to become widely spread, as farmers need proof before they invest. However, the ROI for drones in agriculture is compelling and farms of any size are starting to take advantage of the UAV technology.
There are many precision agriculture applications, the most seducing being to detect weeds, pests, fungi and crop infestation earlier, faster and cheaper than traditional crop scouting.
To assess the health of crops from the sky, you need a:
· drone
· camera sensor
· post processing software that turns the images captured by the camera into crop health maps
The types of crop analysis you can do depend on the functions of your camera.
You can check here how you can apply the Visible Atmospherically Resistant Index (VARI) to images and video captured with a standard camera.
To spot problems before the human eye can see them, you need a camera sensor able to register wavelengths that are invisible to the human eye such as the near infrared (NIR) spectral band.
As this technology is becoming more and more popular, lots of different manufacturers offer professional cameras specifically designed to be carried by drones and to capture quality data.
In this blog post, we want to give a general overview of the top 3 NIR sensors available on the market today.

Here are the top 3 high-end near-infrared cameras for drones in agriculture:
1. MicaSense RedEdgeTM

RedEdgeTM is an advanced multispectral camera specially designed for small unmanned aircraft systems. It’s a rugged, built-to-last, professional multispectral sensor that captures specific wavebands needed for accurate plant health analysis. With various integration options, it’s also one of the most flexible solutions on the market. Additionally, it has optimized GSD, a low power requirement, and a global shutter for distortion-free images.
