描述

SparkFun 迷你光譜紫外線感測器 - AS7331 (Qwiic)

SparkFun Qwiic 迷你光譜紫外線感測器採用 ams OSRAM ©的 AS7331 紫外線感測器。它以高靈敏度和準確度測量三個通道的紫外線輻射:UVA (320-400nm)、UVB (280-320nm) 和 UVC (200-280nm)。 AS7331 上的三個通道均具有內建幹擾濾波器的單獨光電二極體。這款迷你尺寸分線板只有 0.5 吋。 1 英吋。大,有三種操作模式:單次測量(CMD)、連續測量(CONT)、同步啟動(SYNS) 和同步啟動和結束(SYND),在測量之間具有自動斷電序列,以實現所有三種模式的低電流消耗模式。

AS7331 透過 I 2 C 進行通信,因此,自然地,該迷你分線器將 I 2 C 總線引腳(3.3V、GND、SDA 和SCL)路由到Qwiic 連接器以進行無焊組裝,同時還將其路由到0.1 英吋間距的板底部的通孔接頭適合喜歡焊接連接的使用者。該接頭還包括​​感測器的中斷和同步引腳。 AS7331 有四個 I 2 C 位址(預設:0x74),透過調整板背面的 A1 和 A0 焊接跳線來設定。

我們編寫了一個 Arduino 庫,以便您可以輕鬆快速地開始配置 AS7331 並從感測器接收紫外線輻射資料。透過 Arduino 庫管理器工具搜尋「SparkFun AS7331」來下載它,或從「文件」標籤中連結的 GitHub 儲存庫下載它。

文件與資源

This SparkFun Qwiic Mini 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. 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 & End (SYND), with an automatic power-down sequence between measurements for low current consumption in all three modes.

The AS7331 communicates over I2C, so naturally, this mini breakout routes the I2C bus pins (3.3V, GND, SDA, and SCL) to a Qwiic connector 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.

We'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.
