AS7262 - 6-channel visible light / color spectrum sensor - Adafruit 3779

Description

The module is equipped with 6-channel sensor of spectrum, i.e. the spectrum of visible light.It allows you to measure and to characterize how different materials absorb and reflect light waves. 6 channels can detect the colors: red, orange, yellow, green, blue and purple. It detects the wavelength range seen by the light of 450, 500, 550, 570, 600 and 650 nm, each with a 40 nm of full width of half of maximum detection.The sensor communicates using I2C and UART interface using AT command.Additionally, on board is a temperature sensor that can be used to read system's temperature and helpful LED with the power of 5700K, which is used to illuminate the objects.

     

The product is compatible with Arduino

A detailed description along with sample code can be found inthe user guide.

Library is available onthe GitHub.

Pins

Module AS7262 has two communication interfaces: I2C and serial. The default is the I2C interface. To use the serial interface, it is necessary to put tin on the UART SELECT jumper. For serial communication with the computer, use the USB-to-Serial converter.The board has 2x 7 pins for soldering the goldpin strap of 2.54 mm.

Pin Description Vin Power supply from 3 V to 5 V. 3V3 Supply voltage is 3.3 V. GND The ground of the system. SCL Clock line of the I2C bus. SDA The data line of the I2C bus. RST Reset. TX UART interface - transmitter. RX UARTinterface - receiver. INT The external interrupt, the sensor sends a signal after finished measurement (optional pin). Specification
