描述

The AS7421 hyperspectral NIR Sensor is a versitile spectrometer-on-chip solution that enables the usage of near infrared detection technology for material or substance detection purposes. The technology enables to:

- Identify an object by comparing the measured spectrum with a reference spectrum of an object in a lookup table

- Derive the composition of a sample by evaluating the measured spectrum with a model (teaching methods)

- Signal the relative changes of concentration of a component of an object

- Signal the properties of an object (end user)
