Description:

This is an Ultraviolet sensor that can be used to detect the intensity of UV A and UV B light waves. The VEML6075 bt Vishay has a good conductor for taking measurements, even on a long time solar exposure featuring I2C interface. It can also output the UVI (Ultraviolet Index, the strength of light radiation at a particular place and time) by doing a simple calculation. The values for UVI range from 0 to 11+, and 6 or above indicates a high radiation index - time to use some sunscreen or even stay indoors!

As with most ZIO boards, it incorporates the Qwiic connector to transfer UV data via I2C. Just plug it in and start taking measurements. Check out the code to setup different UV readings.

This great little sensor can use either I2C or SPI interfaces so we made it pretty accessible to switch to SPI. Simply solder the header pins provided on if you want to!
