class adafruit_as7341.AS7341(i2c_bus: I2C, address: int = 57)

Library for the AS7341 Sensor

Parameters:

i2c_bus (I2C) – The I2C bus the device is connected to
address (int) – The I2C device address. Defaults to 0x39

Quickstart: Importing and using the device

Here is an example of using the AS7341. First you will need to import the libraries to use the sensor
import board
from adafruit_as7341 import AS7341
Once this is done you can define your board.I2C object and define your sensor object
i2c = board.I2C()  # uses board.SCL and board.SDA
sensor = AS7341(i2c)
Now you have access to the different channels
channel_415nm = sensor.channel_415nm
channel_445nm = sensor.channel_445nm
channel_480nm = sensor.channel_480nm
channel_515nm = sensor.channel_515nm
channel_555nm = sensor.channel_555nm
channel_590nm = sensor.channel_590nm
channel_630nm = sensor.channel_630nm
channel_680nm = sensor.channel_680nm

property all_channels: Tuple[int, ...]: The current readings for all six ADC channels

astep: UnaryStruct

The integration time step size in 2.78 microsecond increments

Return type:: int

atime: UnaryStruct

The integration time step count. Total integration time will be (ATIME + 1) * (ASTEP + 1) * 2.78µS

Return type:: int

property channel_415nm: int: The current reading for the 415nm band

property channel_445nm: int: The current reading for the 445nm band

property channel_480nm: int: The current reading for the 480nm band

property channel_515nm: int: The current reading for the 515nm band

property channel_555nm: int: The current reading for the 555nm band

property channel_590nm: int: The current reading for the 590nm band

property channel_630nm: int: The current reading for the 630nm band

property channel_680nm: int: The current reading for the 680nm band

property channel_clear: int: The current reading for the clear sensor

property channel_nir: int: The current reading for the NIR (near-IR) sensor

property flicker_detected: int | None: The flicker frequency detected in Hertz

property flicker_detection_enabled: bool: The flicker detection status of the sensor. True if the sensor is configured to detect flickers. Currently only 1000Hz and 1200Hz flicker detection is supported

property gain: int: The ADC gain multiplier. Must be a valid adafruit_as7341.Gain()

initialize() → None: Configure the sensors with the default settings
