综述
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)

本产品适用于以下应用:
- Reflective object spectral sensor for material analysis in home/industrial applications
- Fabric identification and detection
- Moisture measurements in industrial, home appliance and agricultural applications E.g.: control drying process of grain, coffee beans to monitor quality
- Fruit & foodstuff parameter measurements before and after harvesting
- Floor type and moisture detection of surfaces in home and industrial robotics
