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

AS7421 Eval Kit
The AS7421 Evaluation Kit enables to perform own measuremens with the 64-channel NIR Spectrometer-on-chip. With the simple teaching methodoligy of the GUI it enables testing multiple applications such as: material or fabric identification, moisture-based measurements, as well as machine learning capabilities. Other customer sample applications are the measurement of brix and dry matter in fruits (sweetness, freshness) as well as quanitfication tasks such as cocoa content measurement in chocolate bars. The Kit comes with calibration tools and sample codes, to use in own application tests.
