GY-AS7262 AS7263 AS7341 visible light infrared color color spectrometer sensor module

AS7262 is a solution designed by a sensor designed to solve the application of spectrum ID.

This chip is a highly integrated device, which can provide 6 -channel multi -spectrum in the visible light wavelength range of about 430nm to 670nm. The full width half high (FWHM) is 40nm.Provide an integrated LED drive with a programmable current for electronic shutter applications.AS7262 integrates Gaussian filter into the standard CMOS. Silicon is used through nano -optical sedimentary interference filtering technology and packaged in LGA packaging. The package provides a built -in pore diameter to control the light of the sensor array.Control and spectral data access can be implemented through any of the following forms: I²C register group, or with a high -level AT spectrum command set through serial UART.

Sensor module as7343:

Product Description:

14 channel AS7343 chip is encapsulated in a flat packaging of 3.1mm × 2mm × 1mm. Like a spectrometer, the sensor is used to measure the spectral power distribution of the spectrum of light source or reflective light.The sensor has 12 equal -spacing measuring channels in the visible optical spectrum, adjacent to a near -infrared (NIR) channel, and has the XYZ function.The difference between its predecessor AS7341 is that AS7343 combines multi -channel spectral sensors and XYZ technology.The XYZ channel is closely aligned with the CIE 1931 xyz color space, which is the standard model of human eye perception color.AS7343 can generate a direct XYZ value, that is, color coordinates, users can flexibly choose whether to perform full spectral analysis or simple color scan.

AS7343 can generate unique spectral features for any light source and reflex light. Asuble six channels can be used at the same time, and the performance is more flexible.The sensitivity of this new product is 4 times that of the previous generation of AS7341, which achieves better color balance perception and signal analysis in the spectrum. At the same time, automatic ADC reconstruction also provides faster multi -channel readings.

In applications such as plant lighting, a single AS7343 sensor is usually sufficient, and it can provide high -resolution measurement of spectral power distribution.If a higher resolution is required, the filter curve of two or more AS7343 sensors can be configured to overlap to reduce the bandwidth of each channel and improve the measurement resolution.This technology can also be used with AS7341.In addition, the AS7343 sensor can analyze chromatographic analysis of liquid or materials to support garden planting applications, such as the measurement of plant chlorophyll concentration.

Another scene of AS7343 is the detection of smoke and heat alarm for the detection of smoke spectrum characteristics.The spectral analysis of AS7343 enables the smoke sensors to distinguish the different types of smoke of burning wood, plastic or water vapor.

Product characteristics:

· 14 optical channels are distributed on VIS, including xyz and a near infrared

· Including 2 additional channels: the channel without filter, flashing channel

· 6 parallel ADC for signal processing
