The gator:UV is the perfect tool to monitor the UV exposure in your next experiment. With the VEML6070, the gator:UV can easily be used to measure the levels of UVA (320-400 nm) radiation. This tutorial will show you how to get started using this UV sensor with the gator:bit (v2) in the micro:bit development environment.
Required Materials
To get started, you'll need a micro:bit to control everything. You can purchase one individually on in a kit.
