Compared to low cost CdS cells, this sensor is more precise, allowing for exact lux calculations and can be configured for different gain\/timing ranges to detect light ranges from 188 uLux up to 88,000 Lux on the fly.\u003c\/p\u003e\n\u003cp\u003eThe best part of this sensor is that it contains both infrared and full spectrum diodes! That means you can separately measure infrared, full-spectrum or human-visible light. Most sensors can only detect one or the other, which does not accurately represent what human eyes see (since we cannot perceive the IR light that is detected by most photo diodes) This sensor is much like the TSL2561 but with a wider range (and the interface code is different). This sensor has a massive 600,000,000:1 dynamic range! Unlike the TSL2561 you cannot change the I2C address, so keep that in mind.\u003c\/p\u003e\n\u003cp\u003eThe built in ADC means you can use this with any microcontroller, even if it doesn't have analog inputs. The current draw is extremely low, so its great for low power data-logging systems. about 0.4mA when actively sensing, and less than 5 uA when in power-down mode.\u003c\/p\u003e\n\u003cp\u003eAs if that weren't enough, Adafruit have also added \u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\" target=\"_blank\"\u003eSparkFun qwiic\u003c\/a\u003e compatible \u003ca href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\" target=\"_blank\"\u003eSTEMMA QT\u003c\/a\u003e connectors for the I2C bus so you don't even need to solder.
