# MicroPython-SI1145
## SI1145: A digital sensor of UV Index/IR/Visible Light/Proximity
The SI1145 is a sensor from Silicon Laboratories with a calibrated light sensing algorithm that can calculate UV Index.
### DataSheet:
https://www.silabs.com/documents/public/data-sheets/Si1145-46-47.pdf
### Features:
- IR Sensor Spectrum: Wavelength: 550nm-1000nm (centered on 800)
- Visible Light Sensor Spectrum: Wavelength: 400nm-800nm (centered on 530)
- Voltage Supply: Power with 3-5VDC
- Output Type: I2C address 0x60 (7-bit)
- Operating Temperature: -40°C ~ 85°C
## Driver version for developers
The driver version for developers (si1145-dev.py) is slightly larger in size as it contains comments to help understanding
