ams AS7265X_DEM_ST Demonstrator kit
The AS7265x Demo Kit is a Windows PC-hosted evaluation environment, designed to provide the user an quick-start approach to spectral sensing. The demo kit consists of the evaluation board, USB-UART cable with Micro-USB connector, and a USB stick which includes drivers, documentation and graphical user interface. The demo board includes unpopulated device pads for the installation of standard LED light sources suited to the specific spectral needs of the application. By default, the LED pads are unpopulated. If necessary also a housing can be provided on request.

ams AS7341 – 11-Channel Spectral Color Sensor
AS7341 is an 11-channel multi-spectral sensor for color detection and spectral analysis applications. The spectral response is defined in the wavelengths from approximately 350nm to 1000nm. 6 channels can be processed in parallel by independent ADCs while the other channels are accessible via a multiplexer. 8 optical channels cover the visible spectrum, one channel can be used to measure near infra-red light and one channel is a photo diode without filter (“clear”). The device also integrates a dedicated channel to detect 50Hz or 60Hz ambient light flicker. The flicker detection engine can also buffer data for calculating other flicker frequencies externally. The NIR channel in combination with the other VIS channel may provide information of surrounding ambient light conditions (light source detection). The device can also be synchronized to external signals via pin GPIO. AS7341 integrates filters into standard CMOS silicon via Nano-optic deposited interference filtertechnology and its package provides a built in aperture to control the light entering the sensor array. Control and Spectral data access is implemented through a serial I²C interface. The device is available in an ultra-low profile package with dimensions of 3.1mm x 2mm x 1mm.
