描述

SparkFun Spectral Sensor Breakout – AS7263 NIR (Qwiic) 近紅外線光譜感測模組

SparkFun Spectral Sensor Breakout – AS7263 NIR (Qwiic) 近紅外線光譜感測模組 將光譜技術帶到您的手掌上，使得測量和表徵不同材料吸收和反射不同波長的光的方法變得更加容易。AS7263 Breakout的獨特之處在於能夠通過I ² C接口和使用AT命令的串行接口進行通信。由於連接在電路板上的Qwiic連接器，連接起來非常簡單 – 只需將Qwiic電纜的一端插入分支，另一端插入Qwiic屏蔽中的一個，然後將電路板堆疊在開發板上。您將準備上傳草圖以立即開始進行光譜測量。

AS7263光譜儀檢測610,680,730,760,810和860nm光線的可見光範圍內的波長，每個光束具有20nm的全寬度半最大檢測。該板還有多種方式讓您照亮物體，您將嘗試測量更精確的光譜讀數。有一個專門為此任務挑選的板載LED，以及兩個引腳來焊接您自己的LED。

The SparkFun AS7263 Near Infrared (NIR) Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS7263 Breakout is unique in its ability to communicate by both an I²C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board — simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic shields, then stack the board on a development board. You’ll be ready to upload a sketch to start taking spectroscopy measurements in no time.

The AS7263 spectrometer detects wavelengths in the visible range at 610, 680, 730, 760, 810 and 860nm of light, each with 20nm of full-width half-max detection. The board also has multiple ways for you to illuminate objects that you will try to measure for a more accurate spectroscopy reading. There is an onboard LED that has been picked out specifically for this task, as well as two pins to solder your own LED into.

The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
