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 \u003cstrong\u003e22-bit dynamic range\u003c\/strong\u003e for ambient light detection from \u003cstrong\u003e0.045 lux to about 188 lux\u003c\/strong\u003e 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, \u003cstrong\u003euniversal I2C\u003c\/strong\u003e. We put this sensor on a breakout board with a \u003cstrong\u003e3.3V regulator\u003c\/strong\u003e and \u003cstrong\u003elogic level shifter\u003c\/strong\u003e so you can use it with \u003cstrong\u003e3.3V or 5V\u003c\/strong\u003e power\/logic microcontrollers.
