"This little sensor is a great way to add UV light sensing to any microcontroller project. The VEML6070 from Vishay has a true UV A light sensor and an I2C-controlled ADC that will take readings and integrate them for you over ~60ms to 500ms." See [VEML6070 UV Sensor](https://learn.adafruit.com/adafruit-veml6070-uv-light-sensor-breakout/overview) for more information.
_Note: before the VEML6070 can be used with Tasmota, make sure it's enabled. To enable it, remove the forward slashes before this line before you compile and upload tasmota to your Wemos device._
```
#define USE_VEML6070 // Add I2C code for VEML6070 sensor (+0k5 code)
```
