The Adafruit AS7262 is a 6-channel visible light spectral sensor from AMS that measures light intensity across six specific wavelength bands: violet (450 nm), blue (500 nm), green (550 nm), yellow (570 nm), orange (600 nm) and red (650 nm). Readings are available as raw 16-bit values or calibrated floating-point values over I2C.

The breakout includes an SPI flash chip pre-programmed with device firmware, a 3.3V regulator, I2C level shifting, and a built-in LED flash for reflecting light off objects for improved colour detection. A UART interface (AT command compatible) is also available as an alternative to I2C.

Key Features

• 6 Spectral Channels – Silicon interference filters at 450, 500, 550, 570, 600 and 650 nm
• Calibrated Output – Raw 16-bit or calibrated floating-point readings
