The MAX44009 makes your life easier by calculating the lux, which is an SI unit for light. You'll get more consistent readings between multiple sensors because you aren't dealing with some unit-less values.\u003c\/p\u003e\n\u003cp\u003eThe sensor has 22-bit dynamic range for ambient light detection from 0.045 lux to about 188 klux with resolution down to  0.045 per least-significant-bit. It does come with software-adjustable integration times, or you can have it auto-range for you.\u003c\/p\u003e\n\u003cp\u003eInterfacing is easy - this sensor uses plain, universal I2C. We put this sensor on a breakout board with a 3.3V regulator and logic level shifter so you can use it with 3.3V or 5V power\/logic microcontrollers. \u003ca href=\"https:\/\/github.com\/adafruit\/?q=max44009\u0026amp;type=all\u0026amp;language=\u0026amp;sort=\"\u003eWe have written libraries for Arduino (C\/C++) as well as CircuitPython (Python 3) \u003c\/a\u003eso you can use this sensor with just about any kind of device, even a Raspberry Pi!\u003c\/p\u003e\n\u003cp\u003eAs if that weren't enough, we've also added\u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003e SparkFun qwiic\u003c\/a\u003e compatible \u003cstrong\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\"\u003eSTEMMA QT\u003c\/a\u003e\u003c\/strong\u003e connectors for the I2C bus \u003cstrong\u003eso you don't even need to solder.\u003c\/strong\u003e Just wire up to your favorite micro with a plug-and-play cable to get lux data ASAP.
