# 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:

## 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

```
