{"product_id":"sparkfun-spectral-uv-sensor-as7331-qwiic","title":"SparkFun Spectral UV Sensor - AS7331 (Qwiic)","description":"\u003cp\u003eThis SparkFun Qwiic Spectral UV Sensor features the AS7331 UV sensor from ams OSRAM©. 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. The sensor has four 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\n\u003cp\u003eThe AS7331 communicates over I2C, so naturally, this breakout routes the I2C bus pins (3.3V, GND, SDA, and SCL) to a pair of Qwiic connectors on each side of the board for solderless assembly but also routes them 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\n\u003cp\u003eWe've written an Arduino library to make it simple to quickly get started configuring the AS7331 and receiving UV radiation data from the sensor. Download it through the Arduino Library Manager tool by searching for 'SparkFun AS7331' or download it from the GitHub repository linked in the Documents tab.\u003c\/p\u003e\n\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\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/-cI6wDsUHVM?si=kH6ITPzKJHSkAgG-\u0026amp;start=67\" 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\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 2.7V-3.6V\u003c\/li\u003e\n\u003cli\u003eCurrent Consumption:\n\u003cul\u003e\n\u003cli\u003eActive Measurement: 1.42mA (Typ.)\u003c\/li\u003e\n\u003cli\u003eStandby Mode: 970µA\u003c\/li\u003e\n\u003cli\u003ePower Down Mode: 1µA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eThree UV Channels: UVA, UVB, \u0026amp; UVC\n\u003cul\u003e\n\u003cli\u003eEach with a dedicated photodiode\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eFour Operating Modes:\n\u003cul\u003e\n\u003cli\u003eSingle Measurement\u003c\/li\u003e\n\u003cli\u003eContinuous Measurement\u003c\/li\u003e\n\u003cli\u003eSynchronized Start Measurement\u003c\/li\u003e\n\u003cli\u003eSynchronized Start\/Stop MeasurementHigh Dynamic Range: Up to 3.43E+10 (resolution multiplied by gain range)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e2x Qwiic Connectors\u003c\/li\u003e\n\u003cli\u003eFour Adjustable I2C Addresses\n\u003cul\u003e\n\u003cli\u003eSet through A0 \u0026amp; A1 pins\u003c\/li\u003e\n\u003cli\u003e0x74 (Default), 0x75, 0x76, \u0026amp; 0x77\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/8\/a\/c\/8\/SparkFun_Qwiic_UV_Sensor_AS7331.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/0\/9\/4\/f\/c\/SparkFun_Qwiic_UV_Sensor_AS7331.zip\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/5\/1\/f\/3\/d\/SparkFun_Qwiic_UV_Sensor_AS7331-Dimensions.png\"\u003eBoard Dimensions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/sparkfun.github.io\/SparkFun_Spectral_UV_Sensor_AS7331\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/b\/8\/6\/d\/2\/AS7331_DS001047_4-00.pdf\"\u003eDatasheet\u003c\/a\u003e\u003cspan\u003e \u003c\/span\u003e(AS7731)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003eQwiic Info Page\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_AS7331_Arduino_Library\"\u003eSparkFun AS7331 Arduino Library\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Spectral_UV_Sensor_AS7331\"\u003eGitHub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":50847482020113,"sku":"SEN-23517","price":23.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/sparkfun-spectral-uv-sensor-as7331-qwiic-sparkfun-sen-23517-41723182055619.jpg?v=1735213862","url":"https:\/\/abcd3032.myshopify.com\/ru\/products\/sparkfun-spectral-uv-sensor-as7331-qwiic","provider":"Tayyab Zak","version":"1.0","type":"link"}
