Sentera Adds Two Sensors to Better Assess Crop Health

Sentera is adding to its portfolio of small, lightweight high-precision single sensor product line. The High-Precision NDVI Single and High-Precision NDRE Single improve spectral band separation and more accurately measure vegetation index.

These sensors utilize patent-pending technology and can be integrated onto any unmanned aerial vehicle (UAV); this helps agronomists, consultants, and farmers identify growth issues earlier and with greater precision. The DJI Phantom 4, Mavic, and Inspire can be preinstalled with the sensors or they can be installed by a dealer on a UAV you currently own. 

“We are excited to introduce our High-Precision sensors, offering ag professionals more accurate and affordable crop health data collection options than ever before,” says Eric Taipale, CEO of Sentera. “We’re committed to offering our customers the best tools to make accurate data measurements and especially pleased to offer these capabilities within our smallest and most affordable product line.”

The new sensors make it easier for users to integrate satellite-based and drone-based index data. The High Precision filters more closely match the spectral filtering used on most space-based imagers, but retain the same advantages in image resolution compared with satellites. 

“Digital agriculture is looking for the best sensor for each task. Depending on growth stage, weather, and other factors, that sensor might be on a drone, an airplane, or a satellite,” Taipale continues. “Our High Precision products make it much easier to combine drone data with other sources.”

The company says that unlike the solutions offered by some of its competitors, Sentera’s filtering technology effectively rejects out-of-band leakage before it can contaminate the measurement, which can lead to errors in computing the vegetative index.

“Targeted data capture allows users to filter out ‘spectral noise’ and collect only the isolated emissions in the red, red edge, and NIR bands – true indicators of crop health,” explains Ryan Nelson, chief mechanical engineer for Sentera. “You can be confident that what the sensor identifies as red, red edge, or NIR content is truly within the proper spectral region. This means you are getting the most reliable, accurate, and precise NDVI and NDRE data available today.”

In addition, point-and-shoot cameras that have been converted or drone cameras that have been modified without proper filtering will display out-of-channel leakage, and thereby produce a less accurate index. Sentera’s sensors use specialized filters to capture NDVI and NDRE data that is highly precise.

“With many cameras currently on the market, you’ll see a significant amount of overlap between color channels that affects the accuracy of vegetative health index,” says Nelson. “When developing our High Precision Agriculture Sensor line, we implemented advanced filtering techniques that provide precise spectral data with complete band separation so users can be confident they’re collecting accurate and reliable NDVI or NDRE measurements every time.”

When you combine Sentera’s Precision Agriculture Sensor solutions with AgVault web, desktop, and mobile, users have an end-to-end data capture solution. Precise sensor data seamlessly integrates with AgVault so that real-time crop health data can be analyzed on or off the field.
