Product Description:

Cost-effective remote measurement of incident or reflected Normalized Difference Vegetation Index (NDVI) radiation bands.


NDVI is a measurement of plant greenness correlated with canopy chlorophyll content and leaf area that is used to monitor green-up in the spring and senescence in the fall.

NDVI sensors are used to ground truth NDVI measurements from satellite imagery, and continuously monitor plant health in the field and in controlled environments.

Spectral Response

The NDVI Sensors have the spectral ranges of 650 nm ± 5 nm with 65 full-width half-maximum (Red) and 810 nm ± 5 nm with 65 full-width half-maximum (NIR).

Rugged, Self-cleaning Housing

The domed shapped sensor head (diffuser and body) facilitates runoff of dew and rain to keep the sensor clean and minimizes errors caused by dust blocking the radiation path. Sensors are housed in a rugged, anodized aluminum body and electronics are fully-potted.


The AL-120 Solar Mounting Bracket with Leveling Plate facilitates mounting the upward-looking sensor to a mast or pipe. The AL-100 Solar Sensor Leveling Plate is designed to level the sensor while sitting on a flat surface or mounting to a surface. The AM-400 Two Band Radiometer Mounting Bracket is designed to mount the downward-looking sensors to a mast or pipe.

Output Options

Available with an analog output.

High Quality Cable

Pigtail-lead sensors feature an IP68, marine-grade stainless-steel cable connectors built directly into the sensor head to simplify sensor removal for maintenance and recalibration. Cable is shielded-twisted-pair wire with a TPR jacket for high water resistance, UV stability, and flexibility in cold conditions.
