AS7421 Hyperspectral NIR Sensor

64-channel hyperspectral NIR Sensor

特徴

  • 64 channel photodiode matrix
  • Spectral range 750-1050nm (61 wavelengths, 5nm separation)
  • Integrated NIR LEDs to cover range from 750nm to 1050nm
  • Integrated micro optics to limit angle of incidence of sensor (Micro Lens Array)
  • 16 independent ADCs with programmable gain and integration time
  • Typical integration time for 64 channel is 262ms - I²C interface and interrupt
  • Power consumption (typ): 2,5mA active, 2µA sleep

概要

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) 

本製品は以下の用途に適しています。

  • 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
