Apogee Instruments NDVI sensors provide a measure of surface greenness. — Cost-effective remote measurement of incident or reflected Normalized Difference Vegetation Index (NDVI) radiation bands.

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). The spectral responses can be seen in the graph below.

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.

Mounting

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.

Warranty and Support

All Apogee products are backed by an industry-leading four year warranty and outstanding customer support
