`adafruit_bh1750`

CircuitPython library for use with the Adafruit BH1750 breakout

Author(s): Bryan Siepert

Implementation Notes

Hardware:

Adafruit BH1750 Light Sensor (Product ID: 4681)

Software and Dependencies:

Adafruit CircuitPython firmware for the supported boards: https://circuitpython.org/downloads
Adafruit’s Bus Device library: https://github.com/adafruit/Adafruit_CircuitPython_BusDevice

class adafruit_bh1750.BH1750(i2c: I2C, address: int = 35)

Library for the BH1750 Sensor

Parameters:

i2c (I2C) – The I2C bus the BH1750 is connected to.
address (int) – The I2C device address. Defaults to 0x23.Can be set to 0x5C by pulling the address pin high.

Quickstart: Importing and using the BH1750

Here is an example of using the BH1750 class. First you will need to import the libraries to use the sensor
import board
import adafruit_bh1750
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 = adafruit_bh1750.BH1750(i2c)
Now you have access to the lux value in lux
lux = sensor.lux

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

property lux: float: Light value in lux.

mode: The capture mode for the sensor. See Mode for valid values.

resolution: The resolution of the sensor. See Resolution for valid values.

class adafruit_bh1750.Mode: Options for mode. Valid values are SHUTDOWN, CONTINUOUS, and ONE_SHOT

class adafruit_bh1750.Resolution: Options for resolution Valid values are LOW, MID, and HIGH
