Light Sensor

Notice: The SI1145 light sensor is no longer stocked or available from Adafruit. We are working on an alternative sensor replacement at this time. You can use the DFRobot Ambient Light Sensor with some slight modifications on the Particle Boron/Argon but we are still testing this sensor at this time.

The light sensor measures levels of visible light, infrared (IR), and ultraviolet (UV) radiation. It operates by detecting electromagnetic radiation through photodiodes sensitive to specific wavelengths of light. The Adafruit SI1145, based on the SiLabs sensor, is used for this purpose.
