crop circle ACS-470 multi-spectral
Crop canopy sensor

The Crop Circle ACS-470 active crop canopy sensor provides classic vegetative index data as well as basic reflectance information from plant canopies and soil.

Unlike passive radiometric light sensors, the Crop Circle ACS-470 is not limited by ambient lighting conditions— measurements can be made day or night due to its unique, patented (pending) light sensor technology.

For on-the-go applications, the Crop Circle ACS-470 sensor can be mounted to virtually any type of vehicle to remotely sense and/or map plant or crop canopy biomass while driving through a field. The compact size and low weight design allows Crop Circle to be easily adapted to pole-mounted and handheld applications. Information produced by the sensor can be utilized to quantify the impact of nutrients, water, disease or other growing conditions on plants or crops.

MULTI-CHANNEL SPECTRAL CONFIGURABILITY

The ACS-470 incorporates three optical measurement channels. A unique feature embodied in the ACS- 470 sensor is the user’s in-field ability to select optical measurement bands of interest thereby allowing the instrument to be spectrally customized to a particular sensing application. Spectral configuration is performed via the use of standard 12.5 mm interference filters.

COLLECT DATA EASILY

Using the Holland Scientific GeoSCOUT GLS-400 datalogger, data can be easily and quickly recorded to a text file on an SD flash card. Additionally, by connecting a GPS receiver to the GeoSCOUT, data collected from the ACS-470 can be georeferenced and stored for later analysis in third party GIS software.
