It measures UV radiation on three channels: UVA (320-400nm), UVB (280-320nm), and UVC (200-280nm) with high sensitivity and accuracy. The three channels on the AS7331 each have individual photodiodes with built-in interference filters. This Mini-sized breakout board is only 0.5in. by 1in. big and has three operating modes: Single Measurement (CMD), Continuous Measurement (CONT), SYNchronized Start (SYNS), and SYNchronized Start \u0026amp; End (SYND), with an automatic power-down sequence between measurements for low current consumption in all three modes.\u003c\/p\u003e \u003cp\u003eThe AS7331 communicates over I2C, so naturally, this mini breakout routes the I2C bus pins (3.3V, GND, SDA, and SCL) to a \u003ca href=\"\/nl\/search?q=qwiic+cable\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\"\u003eQwiic connector\u003c\/a\u003e for solderless assembly but also routes it to a 0.1in.-spaced through-hole header on the bottom of the board for users who prefer a soldered connection. This header also includes the sensor's Interrupt and Sync pins. The AS7331 has four I2C addresses (default: 0x74) set by adjusting the A1 and A0 solder jumpers on the back of the board.\u003c\/p\u003e \u003cp\u003eWe've written an \u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_AS7331_Arduino_Library\"\u003eArduino library\u003c\/a\u003e to make it simple to quickly get started configuring the AS7331 and receiving UV radiation data from the sensor.\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/docs.sparkfun.com\/SparkFun_Spectral_UV_Sensor_AS7331\/introduction\/\"\u003eGet Started with the Sparkfun AS7331 Spectral UV Sensor Guide\u003c\/a\u003e\u003c\/p\u003e \u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/-cI6wDsUHVM?si=zLNd_oK0NaNNSIZA\u0026amp;start=68\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e \u003ch2\u003eFeatures\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eOperating Voltage: 2.7V-3.6V\u003c\/li\u003e \u003cli\u003eCurrent Consumption: \u003cul\u003e \u003cli\u003eActive Measurement: 1.42mA (Typ.)\u003c\/li\u003e \u003cli\u003eStandby Mode: 970µA\u003c\/li\u003e \u003cli\u003ePower Down Mode: 1µA\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eThree UV Channels: UVA, UVB, \u0026amp; UVC \u003cul\u003e \u003cli\u003eEach with a dedicated photodiode\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eFour Operating Modes: \u003cul\u003e \u003cli\u003eSingle Measurement\u003c\/li\u003e \u003cli\u003eContinuous Measurement\u003c\/li\u003e \u003cli\u003eSynchronised Start Measurement\u003c\/li\u003e \u003cli\u003eSynchronised Start\/Stop Measurement\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eHigh Dynamic Range: Up to 3.43E+10 (resolution multiplied by gain range)\u003c\/li\u003e \u003cli\u003e2x Qwiic Connectors\u003c\/li\u003e \u003cli\u003eFour Adjustable I2C Addresses \u003cul\u003e \u003cli\u003eSet through A0 \u0026amp; A1 pins\u003c\/li\u003e \u003cli\u003e0x74 (Default), 0x75, 0x76, \u0026amp; 0x77\u003c\/li\u003e \u003c\/ul\u003e \u003c\/li\u003e \u003cli\u003eQwiic Mini Footprint: 1in.
