# MicroPython-VEML6075
Driver base for the VEML6075 UV Light Sensor
> The VEML6075 senses UVA and UVB light and incorporates photodiode, amplifiers, and analog/digital circuits into a single chip using a CMOS process. When the UV sensor is applied, it is able to detect UVA and UVB intensity to provide a measure of the signal strength as well as allowing for UVI measurement.
### DataSheet:
https://www.digchip.com/datasheets/parts/datasheet/3951/VEML6075-pdf.php (in 09/21/2019) or file ['VEML6075_datasheet.pdf'](https://github.com/neliogodoi/MicroPython-VEML6075/blob/master/VEML6075_datasheet.pdf)
## Key features:
* Package type: surface mount
* Dimensions (L x W x H in mm): 2.0 x 1.25 x 1.0
* Integrated modules: ultraviolet sensor (UV), and signal conditioning IC
* Converts solar UV light intensity to digital data
* Excellent UVA and UVB sensitivity
* Reliable performance of UV radiation measurement under long time solar UV exposure
* 16-bit resolution per channel
* UVA and UVB individual channel solution
* Low power consumption
* Temperature compensation: -40 °C to +85 °C
* Output type: I2C bus
* Operation voltage: 1.7V to 3.6V

## Tests:
#### ESP8266
```python
import veml6075
from machine import I2C, Pin
i2c = I2C(sda=Pin(4), scl=Pin(5))
sensor = veml6075.VEML6075(i2c=i2c)
sensor.uv_index
```
#### ESP32
```python
import veml6075
from machine import I2C, Pin
i2c = I2C(sda=Pin(21), scl=Pin(22))
sensor = veml6075.VEML6075(i2c=i2c)
sensor.uv_index
```
#### LoPy
```python
import veml6075
from machine import I2C
i2c = I2C(0, I2C.MASTER, baudrate=100000)
sensor = veml6075.VEML6075(i2c=i2c)
sensor.uv_index
```
