Adafruit 1777 SI1145 Digital UV Index / IR / Visible Light Sensor I2C
Adafruit Digital Infra-red / Visible Light Sensors with I2C, 5V ready – Adafruit 1777, The Adafruit SI1145 I2C Digital UV Index / IR / Visible Light Sensors use individual visible and infra-red (IR) sensors and calculate the UV index accordingly. They are 3 to 5V compatible and communicate with almost any microcontroller over I2C. Should you need proximity measurements, you can add an IR LED to one of these sensor boards for a detection range between 10 and 500mm. Adafruit supply a free tutorial and library to get you started with an Arduino, but the information should be applicable to most microcontrollers. Supplied as a fully assembled and tested board plus a strip of 01.in. header pins for you to solder on as required. Adafruit 1777 SI1145 Digital UV Index / IR / Visible Light Sensor I2C
