What is the Flora Lux Sensor?
Allow your electronics projects to react to light using Adafruit’s FLORA Lux Sensor, it is substantially more effective than standard photo diodes - designed for the Adafruit FLORA but not limited to it. This sensor is amazingly precise and has a dynamic 0.1 – 40,000+ range of detection, it also picks up full spectrum and infrared light separately from human visible light, enabling great possibilities.

How to get the most out of your project?
The Adafruit FLORA Lux Sensor is connected to your project using the I2C connectors: SCL and SDA, and as it has two sets of SDA and SCL pads – and you can add even more sensors in a chain.
The Adafruit FLORA Lux Sensor is great for wearables as it comes with not just solder pads, but you can sew the pads directly into fabrics and other components also.

There is a dedicated library to allow smoother running and great performance made by Adafruit available here.
