About this item

The SparkFun gator:UV micro:bit Accessory Board (SEN-15273) is a compact ultraviolet (UV) light sensor designed for easy integration with the BBC micro:bit. Built around the VEML6070 sensor, it measures UVA (365 ±10nm) and UVB (330 ±10nm) radiation and communicates via I²C. The board operates within a voltage range of 1.7V to 3.6V and draws a supply current of 480 µA. It offers a UVA resolution of 0.93 counts/µW·cm² and a UVB resolution of 2.1 counts/µW·cm². As part of SparkFun's gator:bit series, it features alligator-clippable pads for straightforward connections. Ideal for educational projects and experiments involving UV exposure monitoring, this accessory simplifies the process of incorporating UV sensing into micro:bit-based applications.
