This is a library for the Si1145 UV/IR/Visible Light Sensor
|
||
|
|
|
||
|
|
Designed specifically to work with the Si1145 sensor in the
|
||
|
|
adafruit shop
|
||
|
|
----> https://www.adafruit.com/products/1777
|
||
|
|
|
||
|
|
These sensors use I2C to communicate, 2 pins are required to
|
||
|
|
interface
|
||
|
|
Adafruit invests time and resources providing this open source code,
