驗菌&螢光兩用儀 組裝

 驗菌&螢光兩用儀 組裝

    一機兩用的儀器，快來了解如何組裝吧！

所需材料：

    最小系統電路板：STM32F103C8T6 Blue Pill板
    麵包板電源：3.3V 5V 12V多路输出
    光源：LED • 600nm-Orange、UV-LED 365nm
    光偵測器：型號 TSL-2561傳感器
    光源選擇指示燈：3色LED模組-RGB
    數值顯示器：0.96寸 藍色IIC通信小OLED顯示屏模塊

上層

---------------------------------------------------------------------

操作

1.首先插上電源即開機，按1選擇所需光源(600nm-驗菌，365nm-螢光計)

2.將Cuvette置於樣品放置處，即開始量測。

  第一行之L值為未換算前的穿透係數。

  按下2可記錄空白組數值(螢幕顯示L0)，按3可記錄待測物數值(螢幕顯示L1)

  完成量測後，連續按4兩下可直接計算獲得待測物之透光率(T)與吸收值(A)
